hi, just debating whether to keep my i5 760 at a 3ghz overclock and get 2 more sticks of 2x2gb corsair (so 4x2gb xms3) or keep it at just 2x2gb xms3 and overclock to 4ghz? what would be better? dont really want to splash out on 2x4gb sticks yet so would just like an opinion on the above settings.

also i have push pull case cooling and a freezer pro 7 heatsink so cooling is fine.

thanks.
 
Run the 760 at 4ghz (should have done that from the beginning !?) and save your money for a future GPU update. You only really need 8gb if doing a lot of video work for instance. It makes very little difference at the moment in games.
 
hmm yer i wanted to do that from the off but a friend has told me i dont need to overclock and that it would just be lowering the life scale of the pc? he said he`d stick with getting 2 more sticks of ram but i agree, 8gb is ott especially for me.

but then again pretty much everyone with a 760 is at 4ghz so it cant be that bad?
 
When you talk about lowering the lifespan of the CPU you're really talking about the difference between 20+years and 15 years... it's still a pretty ****ing long time for a little blob of silicone :)

I've got my C2D running at 4.3GHz, so I'm sure your i5 can handle 4.0 no sweat :)

Get a decent cooler (megahalems/silver arrow/NH-D14) on it and you'll be landed!
 
having problems overclocking now, tried 200x20 to give me 1600mhz ram and a 4ghz cpu clock and even though it intel burns fine after about half an hour the pc kind of shuts down, i think only the psu runs but i get a black screen? iv tried various different settings and it only seems to be happy at 3.33ghz and 1333mhz ram. this is with 2x2gb xms3, memory multiplier is x8.

any suggestions would be hugely appreciated.
 
its a gigabyte h55 board so does it automatically, it says 1.391 vcore in the bios with 200x20, is that about right?
 
ok current settings are

vcore 1.392 (taken from cpuz)
200x20 @4ghz
memory x6 (down from x8) to give 1200mhz ram

see how this goes. is it possible that my board isnt up to an overclock this big?
 
that didnt work either, back to

vcore 1.34v
166x20 @3.33ghz
memory x8 @1333mhz

at a loss now as to whathe problem is

vcore of 1.34 sounds about right.

There is another voltage for the memory controller that needs tweaking as well though. It's called VTT on my MSI board, not sure what it is on Gigabyte. I have this at 1.25v for 4GHz.

It's really important that this voltage is within 0.5v of your RAM or you can brick your CPU.

thanks for that, i had a feeling it could be something to do with the ram. il try and find out what voltage to raise and by how much.
 
thanks for that, ok iv changed the extreme memory profile from disabled (ddr voltage 1.5 qpi voltage 1.5) to profile1 (ddr vltage 1.65 qpi voltage 1.15)

will try 200x20 and x8 for the memory and see how that fairs.
 
ignore that, it wouldnt boot past the bios, iv changed that back and found the qpi/vtt voltage bit, il try it at 1.5v at first, up from 1.10v.
 
sorry yer meant 1.25V, 1.15v didnt work, now on 1.25v and it boots up and seems ok at the momemt.

cpu - 200x20, @4ghz, vcore 1.376
memory - x8, 1600mhz, qpi 1.25v

only thing i havent changed is the dram voltage, that is at 1.5v but my ram is rated at 1.65v do i need change that at all?

thanks again.
 
bsod as soon as i tried to intel burn it.

manually set the vcore to 1.4v and upped the dram to 1.640v, which intel burned fine on standard setting for 5 minutes.

EDIT scratch that it just came up saying it was unstable when i tried again, and yes it was a memory related bsod

Not all CPU's are created equally. Yours might not be capable of 4GHz. Ease off to around 3.6 and work methodically from there to find your limit.
