Glitching after OC

thecremeegg · 13 Feb 2007 at 18:25

Right, today I had a play and OC my system as follows

FSB = 400
Vcore = 1.4
DRAM - Auto
PCI-Ex freq = 100
PCI freq = 33.3
vDimm = 2.1 v

Set the memory timings to 5 5 5 12 which is stock i believe

Basically, in games i can play for a minute then i get graphical glitching, which is just black lines flickering.
What's causing this? my specs are below

Asus P5b vanilla, latest bios
e6400
1Gb of PC2-6400 800MHz Dual Channel GX XTC Gold
Freezer 7 cooler
Hiper modular 480W
x1900xt

According to coretemp its is running at 43 degrees in windows, which i dont think is too high considering its running at 400 FSB

So, any ideas whats causing the glitching?
cheers

what temp is your graphics carD?

thecremeegg · 13 Feb 2007 at 18:28

is there any way of telling that in game? in windows its 58 degrees

thecremeegg · 13 Feb 2007 at 18:59

looked at my bios temps.....55 degrees when not even oc'd :-S i got a freezer 7 cooler or whatever it is and it appears seated correctly, so any clues why tis so hot?

You can use Rivatuner to record temperatures as well as core and memory speeds.

black lines, and they go away at stock?

sounds like the monitor, but not if they go away at stock.

Motherboard monitor 5 will record temp settings over a period of time, though this doesn't sound like the problem.

Is it just a particular game this happens in ?

Check you monitor refresh rates / Hertz ( when i changed graphics cards i forgot to adjust the monitor settings).

I had graphic oddities with BF2 and a change in the refresh rate sorted it.

Its only with COD2 that it happens, was fine before. I can run HL2 lost coast alright with it, no noticeable glitching, so I'll try reinstalling COD2, though I think i need help with gettin the RAM timings and voltage right, im a real noob lol

Everyones a noob to start with

RAM timings and voltages will be unique to your set-up, what works on one will not work on another.

All trial and error , part of the fun

Good Luck

Which settings do I generally have to play with? and do they generally move much from stock (5,5,5,12 in my case)?

Cheers

Well they are your ram timings. The first number usually refered to as been the CAS latency has the biggest effect. The smaller, the faster.

Generally ish the middle numbers added together and added two should be the ideal end number. (ish)

Its generally 5-5-5-12 or 4-4-4-12 with DDR2.

But I dont think that is your problem.

Right, ok, so RAMs fine.....not sure what else it can be other than heat then. Possibly my case is too small, as i've got enough fans in there!
