Would you consider this OC stable?

[wolfman11]

Hello,

Just finished benchmarking the system in my sig this morning with Prime95 torture test running small TFT's. I let Prime95 run 13 hours and 11 minutes and then stopped the test with no errors running at 2.7 gigahertz (HTT=270, LDR=3x). I'd like to be sure this is stable before I go back up to 2750, which was Prime95 stable for 30 minutes before I stopped the test.

I read some posts here and elsewhere and it seems the vast majority of people run Prime95 for 8 or 12 hours - some were recommending 24 hours...is that really necessary? Thanks!

13 is much more than fine. If you can do 12+ at 2750 then clearly you were fine at 2700. Keep in mind a system that is like 2 hours prime stable before failure may be stable for everything you do ever, because the core is not likely to ever reach prime temperatures, for two straight hours during most normal use.

I would consider the processor stable, but not necessarily the system. You still need to test the other components to decide if the system as a whole is stable.

Thanks for the responses.

I'm actually underclocking my ram a bit right now at DDR360 and I've run the Prime95 Blend test for 2 hours and 15 minutes before I killed it with no errors. If I run this for a longer time period does it prove the rest of the system to be stable?

I've been able to run 3dmark2001 and 3dmark2005 with no issues. Thanks.

Prime95 isn't really good for testing the ram. I would use metest86+ the non windows version, otherwise you can't test all of the ram, as windows based programs can't test the ram thats in use and reserved.

I would say that if you could pass all three types of Prime 95 for more than eight hours each, and completely pass the boot up version of Memtest 86 without any errors twice, then your Processor/Mainboard/Memory are stable. For video card, simply run an artifact scanning program(I use ATI Tray Tools, but I believe it does not work for X1800/X1900s) for eight or so hours or have a game that uses all of your video card's features(Any DX9 game should be fine) run for an extended period of time.*


*Keep in mind, some games are not flawless and will crash on stable hardware.

Great, thanks a lot guys! I'll work on this. I'm pretty confident in this RAM as I've had it for about a year and a half now and I ran memtest86 on the machine I took it from. Since I am running it at DDR360 right now do you think it's worthwhile to run the memtest86 loops again?

I installed an AMD quad core heat pipe from eBay today and it appears to have dropped my temperatures about 6C under load (the artic silver 5 says that temps may drop 2-5C additionally after about 200 hours of use). So if I can ensure this overclock is totally stable I plan to leave it here.

Thanks!

y are u running that mint ram at such a slow speed???

set the RAM to the divider above the one u are currently on and see how u get on then...

 

[wolfman11]

The next divider I have available is the 333 (running 266) which would change it from DDR360 to approximately DDR450 - I definately would need to drop back to CAS 3 or so to hit that number and I believe that I read here that the drop from 2-3-2-5 to 3-4-3-8 is worth about 50mhz in RAM speed. Does that seem reasonable? There have been a bunch of "loose vs tight timings" threads around here and dfi-street I was leanig towards favoring the tight timings over the loose ones - sounds like that might be a bad belief?
