What chips on my XMS4400C25?

BigAndy said:
Out of intrest: In screen for Opty i can see that voltage for LDT Bus is quite high (1.47V). Is increasing volts to LDT Bus giving any performance boost or stability?

And wich utillity i should use for testing my RAM's new settings, should it be Prime95, memtest86 or any other???

Stability, it's probably ok with lower volts tbh, didnt really "play" with the opty too much as the X2's arrived.. Its much lower under the X2's and both of them are running a MUCH higher HTT speed

Memtest86 (loop test 5 and 8) give it a 15 min run of each, should ensure you're OS doesnt get hosed. Once in windows, run windows memtest to ~ 1000% to check the rams stable. Memtest86 tends not to show memory instability as well as windows memtest.

If that passes, SP2004 on blend, and chuck in a good session of 3d just in case!
 
I ran SP2004 at the present settings (didn't change anything at the mo) and look what's happened :(

So i need to do something A.S.A.P.

1.66 is too high in general unless you're on Phase or high end water IMHO.

Then what would be max volts on air??? 8)

Sorry Moderators, this is :offtopic: , but i'm really don't see the point to start new thread on this one. So anyone who is going to answer this could you PM me instead of posting it here.

Reply might benefit others, so despite the OT ness of it... 1.6 is the ABSOLUTE max i'd run through a chip 24/7. Should give a decent OC without hurting the life of the CPU to any huge degree... Tend to stick to 1.55 unless anything over nets significant gains

As long as you're temps are under 55 load then anything up to 1.6 _should_ be ok. Max for air would be ~ 1.50 - 1.55 IMHO. Sure other guys here will say otherwise though...
 
I used settings Sacha gave me before:

Picture is like this:

CPU 1.76GHz x8.0 HTT220 1.425V :D

RAM 220MHz @ 2.5-3-3-8 @ 2.71V 1:1

At the mo i'll do quick tests like 30min or so, can't see the point to run SP2004 for 12h every time. When i'll start get some crashes i'll will step a bit back or will do some fine tuning and then will run tests for a longer time. How it sounds to you guy's???

P.S. Next will try 240MHz for RAM ;).
 
So far another 2 tests.

1) CPU 1.92GHz x8.0 HTT240 1.425V

RAM 240MHz @ 2.5-3-3-8 @ 2.71V 1:1

SP2004 was on for 48min-no errors

2) CPU 1.75GHz x7.0 HTT250 1.425V

RAM 250MHz @2.5-3-3-8 @ 2.71V 1:1

SP2004 was on for 35min-no errors
 
Hi there BigAndy, you need to run Mem test that is in your coms mate, and it needs to be run at least for an hour each sesion, you should be able to run the ram at about 260-270 with know errors, when you get to this point let us know and we can start to tighten up the settings a bit for benching, but these setting that i posted are for genral use and this is a good starting point to see how high the memory will go.
 
Hi Everyone!

I left my PC on over the night with Window's memtest raning @ 250MHz 2.5-3-3-8 2.71V 1:1

Test5.jpg


It's been on for more than 9h and no errors, looking good so far :)

I'll try 260MHz next ;)
 
Just keep uping the speed untill you find the rams limit then back of a bit and we can start to tighten the settings up, good work.
 
Yes that would be good but, he needs to find the max speed of his ram first before starting to tighten his settings so like i said just keep uping the speeds to find the max the ram can run stable at, then we will look at lowering the speeds a bit and tighten up the timmings so he will have the best of both worlds.

Your Bypass max is way too low - knock it up to x8 and try again.

Yup, should sort things.

Might be worth dropping the idle cycle a touch too, see if that helps (though it tends not to have a huge affect on stability... failing after such a short period generally indicates a more "serious" issue)
 
OK, the problem is max bypass in my BIOS is only x7 8), anyway i tried to go with it, but i had PC crash with Blue Screen Of Death stright away after it booted in Windows (2 times in a row). And i had one crash with bypass x4 as well.

I think, maybe, i should give a bit more room to breath for RAM and change timings from 2.5-3-3-8 to 2.5-4-4-8 8)... Or i can stay with 2.5-3-3-8 and drop back from 260 to 250MHz...

What do you think guy's???

Cheers
