Q about removing cpu

awhir

srry but say if i take out my cpu can i put a new cpu in my motherboard again.will that work ?

youcancallmeal

It sure will if everythings compatible.
What have got at the moment?

Nukem

As long as the socket type is the same and the mobo supports that type of CPU ya should do. Again need more info

HungryJoey

Or the BIOS supports the perticular core on the CPU or the CPU type, for eg. Some athlon 64 boards do not recognise Semprons unless the latest BIOS is used, or some 939 boards may recognise Winchester core's, but they may not recognise a Venice core if replaced with one.

A quick spec of your comptuers motherboard and CPU would help.

I still have a fond memory of removing a CPU.
.
.
.
It all started when I was changing the motherboard after blowing a thyristor when messing around with the USB backplate which killed the USB connections on the motherboard....though amazinly everything else continued to work fine!

Well after getting the new mobo, I proceeded to remove the Arctic Silver 5 attached HSF from the mobo...but the paste had formed an incredible strong bond with the CPU(had too much on!) and the only way to remove the HSF was to bring the CPU with it.

I placed the CPU in the new mobo and HSF after it...put everything in its place...etc.
Once I powered on...nothing!!!

I started to sweat and time froze......

After completely disassembling the system I saw that I had bent(squashed at 90 degrees!!) 2 pins of the 939!!!
After hyperventilating for a minute or five I decided that I had to try at least to straighten them out before heading off to buy a new CPU.

Using a very small flat head I finally got them straightened out and replaced everything.

It has worked fine from then on....than fcuk!!!

========================================

The moral?
A.
Use only a tiny amount of paste

&

B.
Be gentle with the CPU as they are very delicate!!!!

Direct answer - yes.

But are you asking the right question?

Are you talking about an upgrade or have you been lead to believe that your CPU is damaged ?

If its an upgrade, then you need to check that your motherboard can handle the new CPU. You should be able to find a compatibility list for the motherboard.

Its suprisingly difficult to electrically damage a CPU while its on the board. You have to do some serious messing about with core voltages etc. to do this. If your PC won't boot its more likely to be a bios setting or a damaged motherboard.

Don't forget, a new stock HSF will have a thermal pad, so you won't need thermal paste.

hmm no its just i fell sometimes its my cpu or my ram that cant handel the games and sometimes apps.i have a 3800+ x2 and 1g of ram ? of make think its kingston.but is there any way to find out what is underpressure and i dont think my cpu is sharing the load i find somtimes that 1 of them is try to do a few apps at the same time and its at 100%.

awhir

i also have a asus a8n-sli and a ****y coolmaster heatsink.is it esay to over clock if i get a good heatsink and somemore ram

awhir

and a 7800gtx.

An X2 3800 is a great CPU but its cores are only clocked at 1.8ghz each ( the same as a athon 64 3000) which is the slowest athon 64 available for s939,

Most games are not multi-threaded and therfore cannot take advantage of the second core so one core is doing al the work.

Thats why a single core 3500 would be a lot better for gaming at the minute

You could overclock your 3800 some people get each core to around 2.6ghz on stock voltage which gives more performance than the X2 4800 which is around €800 i think

(UPDATE)The zalman cnps7700 cu is a great cooler you can get it from komplett for €50

http://www.komplett.ie/k/ki.asp?sku=306456&cks=SPK

and with a 7800gtx that rig will do some serious gaming

and 1gig of ram is loads what make is it(UPDATE)

astrofool

a 3800+ runs at 2ghz with 512k cache per core, as far as I remember.

The low end opteron does run at 1.8ghz, but has 1mb cache per core.

1G is plenty of RAM for pretty much anything and afaik that processor is well ahead of any current recommended specs for games. Likewise your graphics.

What OS are you using ?
What AV software ?
Any other info would be helpful.

awhir

its kinston 1024 MB Dual Channel DDR RAM (400)

(GDR 400 dual Channel)

is there any program that can tell me what my ram is.

i have win xp home
nod 32 as av

Cuddlesworth

Only windows xp pro can take advantage of dual core

I think I know what your problem is:

1. AFAIK Win XP home is no good for either 64-bit or dual-core. As far as your OS is concerned you're processor might as well be an Athlon XP 2800.

2. I've never used nod32, but the line 'Microsoft Windows 95 / 98 / ME / NT / 2000 / XP' kinda suggests that its ancient crap and it will cripple your system. Try disabling it, you'll probably get a huge jump in performance.

Try Win XP Pro 64-bit and change your Anti-virus software, you should find a big difference.

astrofool

xp home supports dual core, but not dual cpu (as in two physical sockets on the motherboard).

XP64 doesn't have the driver support yet for general usage.

I used to use Norton AV (paid for), but changed to AVG recently because Norton was such a system hog. AVG doesn't use heuristics apparantly (detects things that might be a virus due to behaviour), but doesn't affect system performance as much.

Also, remember to install the latest motherboard drivers from www.nvidia.com and also to keep windows patched and up to date.

NOD 32 IS THE BEST ANTIVIRUS EVER MADE DONT ASSUME ITS ANCIENT CRAP LOOK AT THE AWARDS IT GOT IT FASTER AND SAFER THAN NORTON AND COSTS LESS TOO

sorry for the caps but dont says its crap when obviously you have never used it, I had to service a Pc running Norton "antivirus" and it was bottlenecking the whole PC I ran nod32 and it found loads of viruses and the system ran smoothly

What on earth? Along with the 7800GTX that's a vicious gaming system. When you say "can't handle", what do you mean? I have a Sempron 3000+ and a 6600GT and it runs any game well at 1024x768 with full detail turned on. Maybe you need 1600x1200? But I think the extra speed of your CPU and video card over my system would make up for that resolution?

Can you tell us what frames per second you're getting in certain games with all the video settings on max? Do you have the latest motherboard and chipset drivers? The latest version of DirectX? The latest patches for the games?


On the other hand, if your system already runs fast, and you just want to splash out and make it run fastER with a new CPU, then yeah, any socket 939 processor above your own should fit and work fine. But if you ask me, anyone replacing a e350 CPU because it's too slow has far more money than sense


edit: and I agree with conzy: making the assertion that software is crap because it claims to support windows 95 is lunacy.

I presume you have used and examined all the other options out there to come to that conclusive, objective reasoning, of course?

What? Why does the fact that they state they support older OSes make you presume that it will cripple the system when its run? All thats being said is that older Windows APIs than just the most recent versions are supported. Unless you know what you're talking about, please stop spouting such BS.

conzy

I have used Mcafee, norton, bullguard and AVG and Nod32 is the best, although AVG is good and its free

And if there is an anti virus that cripples system performance its Norton

awhir

see when i play cs:s on full everthing sometimes i get these huge slow downs for a few secs but sometimes minutes this also happens in world of warcraft.

Balfa

Well that's not your CPU. Is it slow down in ping or definitely drop in frames per second?

It sounds like hard disk access slowing you down. Do you hear the hard disk crunching away like mad while it's happening (or the HDD light come on)? If it's momentary, it's likely to be CS trying to grab a sound from the hard disk that wasn't in memory.

If it's longer than momentary, then it's probably background programs doing something silly. Make sure to close all tasks (for the sake of troubleshooting, close down everything including any tray icons, and consider looking at the running processing and ending what you don't need if you know what you're doing).

Again, for troubleshooting, try lowering the resolution and all detail settings to minimum, and see if it still happens. That will then surely point to hard disk access if it continues to happen.

Just change to winxp -pro-... or maby a horrable net connection.

I don't know (and don't claim to ), but I use AVG and haven't got any viruses in a long time, but then I don't spend much time surfing porn/hack sites.

Its a trade-off between catching every possible virus and allowing your system to actually run. Generally anything with 'realtime protection' is going to be a ball and chain on your system.

zuma

I use Trend Micro PC-Cillin and with the exception of an automatic update which set my CPU to 100% uage it works fine.

Also its NOT a resource hog like Norton which is great.

conzy

Developed by Eset, NOD32 has received more VB100% awards than any other product in history. With a small footprint and fast scanning speed, NOD32 is a favorite choice with gamers and anyone for whom system performance is an issue

Do you beleive me now?? it is the fastest anti virus and doesnt kill system performance like other anti-virus software ahem...norton...ahem

claregalway Qs does the slowdown only happen while playing games online??? and do you HAVE a 7800gtx or are you GETTING a 7800gtx???

DemonOfTheFall

I'd second NOD32 for the least resource hogging and intrusive AV program out there. It silently blocks absolutely everything, only ever pops up with a message from the system tray to tell me when it's got a new update. Used to use AVG but that was missing a lot too much java crap for my liking. NOD32 is the best i've used out of norton, symantec corporate, avg, panda and nod32.

Periodic slowdowns sound like hard drive more than anything. Also, get XP Pro on that machine, you'd might as well have a 3000+ as a 3800+ without dual processor support.

astrofool

As i said before, XP Home supports dual core.

awhir

ok tnx for the help.
and yes i do have 7800gtx

awhir

and is there any point of me upgrading to xp pro wasting my money and then in while after i can get vista.

Yep. Did the same. Except it was quite a few more pins than your 2. Surprisingly, I managed to straighen them all with a sharp knife and the processor went back in with just some minor persuasion. It is still working today and overclocked too.

They should have warning information somewhere obvious.

I don't get it. How did you guys manage to bend the pins? All you do is place the CPU gently on the socket and then lower the arm. It's called a zero insertion force socket for a reason: You don't use any force!

And what sort of warning are you looking for? What do you need to be told not to do that you did wrong?

"Don't brutally manhandle sensitive electronic equipment or it might not work"?

Insertion isn't the problem. To remove the CPU you will need to remove the heatsink/fan first to get access to the release lever. The fool that I was, I just pulled on the heatsink. Unfortunately, the CPU was too attached to the heatsink to let go and it came out of the socket with it. More unfortunate still, the socket also was quite attached to the pins and gave a good fight before finally giving up. As it always happens in this kind of relationship, something broke - some pins got bent. I suspect that this was one of the reason why Intel went with LGAs.

For future reference, you should twist the heatsink off.
