What chips on my XMS4400C25?

[BigAndy]

Can't believe my eyes!!!

:O

300MHz

Only problem is, as i mentioned before, my PC refused to boot with multi x6, so as you can see multi is x7 and it's took CPU up as well. In this case it has been overclocked for 100MHz (2.10GHz).

Excellent mate you have done very well there, you want to try and tighten the memory settings up a bit now as this will make your apps run that bit faster,

 

[Highland3r]

Can you grab a pic of the bios settings used please? Or list them

Cheers

Yes Mete, please. Looks like i wont be able to go any further... I tried 310, but SP2004 crashed after 1min and i got crash with BSOD as well. Looks like 300 is sweet spot .

O yes, could you tell me is there necessary to increase vcore for NB chipset, as i heard somebody saying that when HTT comes to 300 it worth to increase vcore for NB as it will make system more stable, will it?

Good job - nice to see the effort/advise paid off, not sure what left in teh tank at 300mhz - those timing look pretty slick already

OK, give me a little bit time (as i have a card reader on 2nd PC and to work on it need swap VGA aswell (2 PC's 1 VGA )) and i'll sort you out with some pics .

I always can step back to 290 or 280 which still would be nice .

And thanks for pushing me to update BIOS

Cheers

Macerik is right when he says the timings look sweet, this is very true at that speed, what you want to try is benching the ram at this speed and then look at reducing say to 290 or 280 and tighten the settings up a bit, then bench the ram again and see what works best for you.

Very well done mate, everyone hear is helpful.

Hi andy looks very good mate, now try and tighten up the settings to somthing like this.

Sacha mate, can you post A64 screen again in biger format, my eyes is struggle from this small one

How exactly i should tighten up the settings, anyway???

Cheers

Here we go, specialy for you mate .

Odd Divisor Correct to disable and try again mate Rams only running at 262mhz at the mo

What's the catch with this Odd Divisor Correct???

Ram speed is calculated based off the CPU speed.

So in this case, with ODC disabled 300*7 = 2100, 2100/7 = 300 (which is ram speed)

ODC rounds up any odd CPU multi's to the nearest even one.

So the ram is divided by the next even multi, and the CPU speed runs off the current "odd" multi

So in this case: 300*7 = 2100, but with ODC enabled ram speed = 2100/8 = 262

So is it mean that @ HTT 300 my RAM still run's only at 262MHz???

But why CPU-Z reading it as 300MHz???

CPU-z cant "read" the ODC setting yet. Think its corrected in a later release though

<edit> CPU-z 1.33.1 should read ODC correctly </edit>

You was right:

Hi mate sorry about that i have just taken another snap.

 

[maverik-sg1]

I would suspecty 300mhz to be gotten with 3-3-3-8 or 3-4-4-8 with the ram you have - all other timings look as though they should work also.

As you all know things went a bit wrong with this ODC, i thought i was running my RAM with 300MHz, but actualy it was only 262MHz .

I disabled ODC and looks like best i can get out with timings 2.5-3-3-8 is 260MHz (262). Tried 265, but memtest crashed at 415%.

As i was able to run memory @260MHz before with same settings it's mean BIOS update didn'd gave much benefit.

As well i used settings sacha gave and tightened up my RAM @260MHz, but looks like it didn't helped as well, result in Super PI was worse by 0.657s.

I still will do a couple tests with CPU, but as my CPU is capable running @ 2.7GHz (can boot in Windows with 2.85GHz on AIR) i think i should loosen timings to get RAM run @ 270MHz 1:1...

Or would it be more effective to stay at present timings and frequency and run CPU @ 2.60GHz with 1:1???

Cheers

Try 3-3-3-8 FFS do you actually read my posts?

Or try 2.5-4-4-8 - increase the TRFC to 18 also.
