My CPU has been overclock to 3200mhz but is running on such a low v core.

Hi,
my system is: Intel E5200 Overclocked to 3.2GHZ
Asus P5QL PRO
Corsair DDR2 800 Ram O'C to 854
HIS ATi HD 4670 1GB GDDR3 O'C to 850 , 930#
Corsair VX 450w PCU

What the issue is that when i overclock the above, I did some research and it said my stock voltage was 1.2, so i overclocked using 256 x 12.5 giving me the 3.2 set the vcore to 1.2 (reed that you can go to about 3.2ghz on stock voltage) and run prime95 for about 6hrs + 3dmark06 4 times, with not 1 crash, fail.

Most would say so what are you worried about! well after a bit more research i found that other people with same cpu use a vcore of of about 1.34! to archive 3.2!
The software included with my board came with a voltage meter, and it say my vcore is only 1.18v and when i load a game the voltage lowers to 1.17v so whats with that?

I play games maxed out for hours on end with no blue screens so i guess im asking if others think this is ok or should i up the vcore abit.

can include images of what i mean, just ask.

Many thanks

OK, i could not believe that my idle temp on a stock cooler is 23'c and after 6hrs of prime95 temp never went over 46'c.

I might overclock this chip abit more if thats the case, not sure what to yet, ?

There's no way those temps are core readings, you should download core temp to see what the real temps are.

OK, off everest my my 2 core temps 29'c and 31'c but the main cpu temp reading says 23'c.

I built the system to run cool with a total of 7 fans (including cpu, pcu etc) so prob has a lot to do with it.
HIS HD 4670 runs really cool too, according to ati overdrive idle temp is around 33'c and after 1hr of NFS shift is about 44'c

Got same cpu and gfx card as you, my cpu runs 280fsb * 12.5 = 3.5ghz so you can run ya cpu faster without any sweat.

Ok than, What v core are you using with that config?

 

[JMRoe]

Are we related Roe?

RoEy (Roe)

Hah lol! what neck of the woods are you from?

 

[JMRoe]

LOL, Nottinghamshire mate. A small village called Blidworth. You?

RoEy

Not to sure if i have any family in Nottingham but who knows.........!
Im from Peterborough, Cambridgeshire. How old are you?

 

[JMRoe]

26, you? Sorry everyone; slighty off topic.

RoEy

Tell me about it i come on this forum to get advice on me cpu n the next thing im finding other Roe's. what ever next ,lol! Im 24 n just starting to get into computer's this is my first proper build, spent about 3 days researching and learning to overclock before i would even dare go into the bio's, scary stuff! Lol

I found another E5200 overclocked 3.5GHZ with a vcore of 1.14!!!! how about that hey ive been beaten, gonna attempt to O'C this weekend n c if i can push 3.7GHZ with a vcore of 1.2750 Ell post my results.

1 other problem i have is that i can O'C my RAM to 1033 (from800) with auto volt stable, but as soon as i set the volt to manual n set the factory set volts to 1.9 it blue screens
The ram i have is more than capable of archiving 1033 with 1.9v, is ent it?????
And if not is it safe to go over the factory set vcore by lets say no more than 0.3v?
oh yeah the ram is Corsair xcms6400 800mhz DD2.

Ive just started OCing my E5200, its taken me ages to build up the courage to play with BIOS!!!

Ive increased the FSB to 220 so far with a multiplier of x12.5 so 2.75GHZ at the minute.

What else do i need to change as i go further???

Cheers

Hi,as you have overclocked to 2.75Ghz you get the idea of overclocking.
But to get a higher stable overclock you need to do the following:

First you need to set pci out to 100.
As you have already achieved 2.7, with a FBS 220 on auto vcore.
I would go up in 10s up in tell you reach about 256 (3.2ghz)(allowing the system to save new settings and reboot back into the bios) Now it starts to get complicated as long as the computer starts and gets you into the bios carry onto the next instruction.

Setting the vcore, well according to intels website the stock voltage is 1.2v This is enough to power the e5200 at 3.2ghz. So if ya mobo allows you to set the vcore set it to manual and then 1.2v.

Now hit F10 and enter the Operating system, download Prime95 set it all up and now stress test the system for 4hrs if all gos well then go bk into the bios and go further lets say no further then 280 with a multiplier 12.5 vcore of 1.280 giving you 3.5Ghz (dont ever go past this mark on stock cooler).
Repeat above steps to make sure the system is stable.

You can also increase the DRAM frequency easy by setting dram to manual and lets say you are using 800mhz with the e5200 and as long if the ram is good quality you could get the frequency to 950mhz if not higher just make sure you set volts to manual and set it to what ever the stock voltage is!

Its a long and patient matter that needs you to stick at it tell you get it 100% right cause you dont want to be playing crysis and all of a sudden BLUE screen!!!!!!!

Just make shore the must important and most damaging element to overclocking is Vcore never set above 1.34v instant puff of smoke n a high possibility of melting your mobo.

Good luck n hope this helps you as this info took me 3 days to learn.
