Best stress tester for RAM +CPU?

[krishcanag]

Hi

I have been overclocking my CPU and using memtest+ and orthos, runns ok for 1 hr. Then run FSX on XP home and within 10 mins at EGLL it freezes and I have to reset PC. Now inertestingly, it never happens if I relax memory timing or set back to default CPU and BISO settings, which would suggest one of 2 things.

None of the above-mentioned do a full job of stressing the CPU + RAM, or FSX with the add-ons of traffic and secenary create too many file read requests that either the HDD cannot keep up with the faster throughput or its getting lost.
I don't know, but it looks like FSX is a better stress tester than either of the above, be it an expensive tester with add-ons. Or FSX is a leaky peice of s/w when you have add-ons and issues arise!!

I wish someone could post a method of setting RAM timing as you overclock the CPU, also I may be contributing to the this issue bacuse I have 2 sets of 2X 1GB RAM modules, they are not matched purchased 3 months apart.

At default memtest says my memory B/W is nearly 5000m/b, if I set timing for each and increase it to 5300m/b I start getting problems with FSX not orthos or memtest, this with with approx FSB 430.

What is the best method forward?

A good allround stress test is the X3 TC Rolling DEMO. It highlighted errors on my system (using Vista) that Prime95 and Memtest didn't.

There are a huge number of posts covering that on this forum.

Re: Best stress tester for RAM +CPU?

i ran intel burn test, this made my CPU ran upto a max temp of 66 degrees when overclocked to 434FSB. Is this too high? When using orthos it only went upto 55 degrees.

Re: Best stress tester for RAM +CPU?

That test always is hotter 10-20C for sure! And yes, that is fine temp, especially for that test

I would suggest you use the latest Memtest86+ and run 5-10 full passes to be sure, not just a hour >>
Memtest86+ - Advanced Memory Diagnostic Tool

I use Orthos myself as well, Blend test. Plenty of Stability programs posted here >>>

Re: Best stress tester for RAM +CPU?

Its nice to see you back and best wished for the newyear.

Could you check this overclock and comment. Now at default setting memory B/W was 4970MB/s with this loose timing it is 5054MB/s, I have got it to 5350MB/s my either adjusting to 5-6-6-18 or adjusting static thread but not sure if it stable, what would you expect from my memory normally, though my 4GB is 2 independent 2X 1GB sticks!!!

Re: Best stress tester for RAM +CPU?

Thanks for the kind words! I wish you a Happy New Year as well!!!

You should be able to use 555-15/18 at that speed, and on the B strap you should be able to use 6-8 tRD (Static tRead) have you tried lower MCH Voltage yet? I would start there, maybe 1.22-1.24 and if that works then try lowering your tRD

If 555-15/18 does not work then Likely one of those advanced timings being in Auto is the problem

[krishcanag]

Re: Best stress tester for RAM +CPU?

ok, I will try 1.26 and then look at lowering timings

[Lsdmeasap]

Re: Best stress tester for RAM +CPU?

Good luck, and let us know how you get along

[krishcanag]

Re: Best stress tester for RAM +CPU?

I did a quick test to see if I am heading in the right direction. MCH 1.26 seems to be stable.
I changed timings from 5-7-7-24 to 5-5-5-18, nothing else, it took 3 times longer to bring up the windows login screen!!! so put it back, hmmmmm
not sure what to do now, doesn't ever seem to like me putting tighter timing.

[Lsdmeasap]

Re: Best stress tester for RAM +CPU?

Sounds like you should maybe manually set all your timings, Please post a screenshot of what auto is giving you. Use this program Memset >>>

Re: Best stress tester for RAM +CPU?

Hi

I hope this is what you want.
Note: I have manually set static thread at 9, not sure which is is that, performance level = 9? is that it?

[krishcanag]

Re: Best stress tester for RAM +CPU?

this is the default (optimised defaults loaded.

[krishcanag]

Re: Best stress tester for RAM +CPU?

Hi

I have got it stable and running at 5-5-5-15 by adjusting some other timing. The mem b/w is now 5300MB/s. I am not sure if I want to adjust anyhting unless there is something that is really out.

Re: Best stress tester for RAM +CPU?

I used to run prime for 40 hours and memtest overnight and now i use occt put it on for 24 hours and it has found faults the others didn't seems a reliable little program for testing a pc.

What format do you use, is it the MIX option?ie., CPU + RAM?
