Passes mem and pi but cant game?

TheCrow · 28 Aug 2006 at 20:18

x2 3800+ @ 2.6, 1.4v

temps all ok.

Passes Mem test and can do super PI, but will blue screen when i play CSS.

Any sugestions?

welshtom · 28 Aug 2006 at 20:21

test for stability maybe?

Jokester · 28 Aug 2006 at 20:21

SuperPi isn't a particular great stability test, try Prime Small FFT and see if that fails quickly.

ye it failed prime very quickly (test 1)

Iv knocked it back to 1.5 and HTT x 4 (had it at 3) - now it seems fine (well it hasent failed yet test 4)

So what has this told me? - ie what should i do to move forward? i liked 2.6

up the voltage a notch at 2.6

1.45v

It is probably is in need of more volts as suggested by welshtom but it might also be power supply, you will be pulling more power whilst gaming.

Just a thought so it might be worth checking voltage rails too.

TheCrow · 28 Aug 2006 at 22:56

any good programs for watching the rails?

gunner · 28 Aug 2006 at 23:00

Try OCCT stress test it gives you detailed graphs of your rails once you pass its 30min test.

TheCrow · 28 Aug 2006 at 23:50

I took it right back to 2.2 cos i know its stable at that but they dont look the best in those graphs :eek:

What do u lot think:

This seems too far out for my taste?

w3bbo · 29 Aug 2006 at 07:32

Those voltages are well within spec...look fine to me.

TheCrow · 29 Aug 2006 at 08:23

even the 12v? :confused:

gunner · 29 Aug 2006 at 08:58

The 12Volt is not as bad as it looks as its only 0.64% out. My Hyper 580W has a 0.5% variation and its okay.

What RAM are you using. I found my overclocks were much better with G.Skill ram than my older generic stuff even though it passed memtest without errors. Suddenly could get 2.6 stable whereas before I was stuck at 2.2Ghz.

TheCrow · 29 Aug 2006 at 11:00

Iv got Geil 2GB PC3200 (This stuff) was running it a 166 to get above 2.2.

At work just now so cant rember all the stuff but i not good with RAM so have just left it basicly std apart from the divider.

Seriously you will need to follow Tom's advice. I'm fairly sure thats why your clock is unstable. Give it a go, but watch the temps. Good luck.

TheCrow · 29 Aug 2006 at 15:21

ill give it a go. Cheers.

TheCrow · 8 Sep 2006 at 23:52

not stable at 2.6 @ 1.45v

got a new cooler Frezer 64Pro, works very well, sitting at 40* at full load 2.6 @1.45v. It comes unstable at 2.65 so think ill just keep it here for a while.

But.....if i was to go further how far can i push the V-Core?

Nami · 9 Sep 2006 at 15:49

My vcore sits at 1.504 according to CPU-Z (altho there is always inaccuracy with these software voltage monitors) and is happy enough

I put even more voltage thru my previous venice, around 1.6v I seem to remember, cooled by an Thermalright XP120.
