Are my memory timimngs ok?

Thanks.

Mikey1280 · 3 Jun 2006 at 21:13

what memory is it?

cymatty · 3 Jun 2006 at 21:16

Mushkin red extreme performance PC3200 (991439)

Mikey1280 · 3 Jun 2006 at 21:22

Are you sure the product code is correct? This is what google comes up with

'Mushkin DDR PC4000 Memory 991439, 512MB 500MHZ, 184 Pin, Unbuffered, non-ECC, CAS 2-2-2-6'

Do you happen to know the stock timings?

The memory is supposed to be pc3200 (200mhz), however it will run at pc4000 (250mhz) @3.4v, if that makes sense.

Timings at 250mhz? I assume 2-2-2-6?

They are set at auto in the bios apart from the Trc which i have set at 8 after someone told me it that Trc should be RAS+Tras.

Ok, you might be able to change the RAS to CAS delay to 2. Run memtest after you do this before you boot into windows. Otherwise I would say they are very nice

Ok cheers, do you think i will be able to get much more out of this memory? or is what i have good enough?

Thanks

Mikey1280 · 3 Jun 2006 at 22:24

Its fine, doubt you'll be able to get that much more

Ah ok cheers, it will take 3.5v i am only giving it 3.4v (which it needs to get to 250mhz) i have just seen a review where they ran these sticks at 270mhz@ 1.5,2,2. :eek:

Me wants to do that now.

Although i should imagine it will kill my sticks.

These are UTT based modules, so you should try getting tRCD from 3 to 2 for a little boost. 260 is an excellent clock though, I hope you have some active cooling over your modules though, I bet they're getting hot.

You can try Cas 1.5, it may well work, it only makes a small difference over CAS2 (A64 mem controller doesn't really support it properly or something along those lines).

Yes i have a 80mm fan over them, although at 3.4v@ 250mhz they were not even warm to the touch, even after 3 hours prime, so the cooling must be working.

Had more to give but on standard cooling died, hmm should i get better cooling?

Prob need a combination of more volts + better cooling, around 270 even the very best kits need lots of volts.

Did you trying changing tRCD from 3 to 2?

cymatty · 4 Jun 2006 at 12:39

No not yet i was just seeing what i could get out of the memory, i think it would stop somewhere around there. I could increase the voltage to 3.5v without prolbem, however i think its the cpu that is holding me back i think i need more voltage, so i need an aftermarket cooler however is it worth it to get from 2.6-2.7 :confused:

With UTT you'll get as far at 2-2-2 as 2-3-2 mate (atleast you SHOULD do, nothing is guarenteed).

As for using an aftermarket CPU cooler, you could get a Freezer 64 Pro for cheap I guess, that might gain you a couple of hundred more mhz

Well i know its my cpu as it wont prime at 2.75ghz with my ram runnig at 250mhz. I am currently putting 1.525 volts through my cpu what would i be able to put through it with a Frezzer pro?

With good case airflow you should be ok with 1.6V

Also when running high Vdimm its better to keep Vcore quite high, running high Vdimm and low Vcore tends to kill chips.

Yeah i read about that, so i am runnig at 1.525v so that should be ok, what about raising the voltage on the nb? Would that be ok on the standard NB cooler? I have heard that can sort out flaky overclocks.

Thanks for the help.
