New bits, bad results?

SteQ · 14 Feb 2006 at 00:31

Hi guys,

Ive just bought some new bits for my computer so that i can try out some overclocking. Problem is, now that i have it all set up, i cant seem to get my PC stable above anything other than default. The only bits that i have changed are:

1) A new case with better air flow
2) My RAM, g.skill 2x1gb (from 2x512mb 3200 Geil Value)
3) Hiper 580 Type R
3) Freezer 64 pro HSF

now, with my old Geil RAM i could get up to a stable 2.2Ghz by increasing the FSB and voltages for the ram and CPU.

I just dont understand it, no matter what i do it doesnt seem to like it. Its a tad annoying having spent quite a bit of money on the new bits. I cant figure it out. Any ideas?

Spec:
AMD64 3200+ winchester
abit av8 3rd eye mobo
2x1gb g.skill pc4000
ATI x800xtpe
Hiper 580 Type R

Use a divider on the ram. Using cpu z what is the memory sitting at at stock?

any chance of a peek at your overclocked settings in u'r bios?

SteQ · 14 Feb 2006 at 12:43

its at 210Mhz at the moment, but its pc4000 and should go to 250Mhz. Its a bit wierd because as i said, ive got it up to 2.2 at 220Mhz using Geil value. And was stable when i upped the voltages to 1.6 and 2.7 on the ram.

Now with the gskill i can only get it up to 2.1 at 210Mhz, anything over and it just throws a hissy fit.

Could be your motherboard or could be the fact your not pushing enough volts through the G.Skill.

Have you got 'cool n' quiet' thingy on?

SteQ · 14 Feb 2006 at 15:28

nope cool n' quiet is disabled. Ive gone through testing my CPU and i can get it to 2.35Ghz at 1.575v, and its stable. Im just about to start testing my RAM, ill post what i find.

SteQ · 14 Feb 2006 at 16:23

i can get the RAM up to 230Mhz at 2.6 volts, but as soon as i need to up the voltage and move to 2.35Mhz with 2.7v it becomes unstable. If i use 2.7v i get the dreaded blue screen of death when loading windows.

Now i believe that pc4000 is supposed to run at 250Mhz. does this mean i have dodgy ram? or is it something else?

well does the ram say it supports 2.7v if not dont tell em you tried or u voided ure warrenty, if u try using a divider (i know that the ram should but is to find out if cpu can take it) and then have the ram run around 200mhz and try upping the fsb on the cpu so that you can find out the max cpu speed, that thing should get much higher than it is. also if the ram still wont run fast then you could try rma and get some different stuff, have you checked that the ram doesnt have known issues with ure board?

SteQ · 14 Feb 2006 at 19:47

It says on the sticks 2.6 - 2.8v, so yes it supports it. Ive already done that iraiguana, and ive got my cpu up to 2.35Ghz it doesnt seem to like going higher. Im beginning to think that it may be my mobo.... but I cant find any evidence of it yet.

who says the memory controller can handle 2gb upto pc4000 speeds. You are running a winnie

Yup certainly a possibility. My overclocked winnie mem controller didn't like going from 1Gb CorsairXL to 2Gb Ballistix ..sent them back and bought a cpu with a decent controller instead.

Thanks tom, i didnt realise that could be the problem. You have put my mind at rest.

ps - ive got it stable at 2.25Ghz without putting a divider on the ram.
