Im I pushing my memory too much

Phil2008 · 17 May 2007 at 21:02

Ive just upgraded to "2x1gb Corsair XMS3500LL PRO DDR" and overclocked it to 265 with timmings of 2.5-3-3-7 1cmd.

Anyone know whats the max this mem will clock to, cos I dont want to push it to its limets cos I have my pc on at least 16hours a day. So if 265 is near its limet I will turn it down?

as long as the volts are not too high and the memory is stable with something like memtest86 then nothing is "too high"

Phil2008 · 17 May 2007 at 22:39

Ive run memtest for about 20 mins now, and ever 30 secs or so it brings up
QX:8012
AX:0212
BX:8600
and so on

Is it ment todo this, when do I stop it, how do I know if its failed or passed??

The huge red messages are the errors. If you're getting them it's failed. It also lists the number of errors.

The QX:8012 etc is the current position it is testing.

Is it ment to be doing this???

And how do I stop it??

You have memory capable of very low latencies, why not use them?

Im guess that the latencies are the timmings? what settings do you recommend?

Nope :/

i had that once - was a duff disk, re download and burn/stick on floppy. and try again

Use the highest multi you can get away with (this will give you the lowest HTT) and lower your timings as much as possible.

Some people have had that ram at 2-3-2-5 @ 230mhz, so assuming your HTT is below that go for those timings.

If your HTT is lower than 210 go for 2-2-2-5

Dont drop any CPU speed though!

Your modules are safe up to 2.9v. If you go that high, I'd definitely suggest a fan directly on the memory for longevity.

Phil2008 · 18 May 2007 at 21:28

Ive decided to go down abit to 253 with timings of 2.5-3-3-7 1cmd

Can you get 2-3-3-6 out of it at that speed?

Maybe, but I dont want the timings too tight cos like i've said my pc is on 16+ hours a day

So what? it wont make a difference to the lifetime of the ram. Will you care if it lasts 6 years instead of 10?

Phil2008 · 21 May 2007 at 12:33

Umm may be not, but still dont like pushing my pc to its limits, you never know it might cause a fire or anything? But saying that, I am pushing my cpu to its limits. But im not too wrorried about the cpu being maxed out cos it idels at 28 - 30c, and its a clawhammer too.

Im guessing your running your memory near stock speed with those timings in your sig?

Its at 207mhz, mine isnt a particalarly good set, some will do 215! Good enough for me though.

A64 = Latency < Frequency

If you want performance memory, get yourself some BH-5 - 265mhz @ 2-2-2-5? Yes please! Only in 512 sticks unfortunatley

The actual stock speed for the 3500LL is 217mhz, so how come you have got yours running lower then the stock speed, just for tighter timings?? I would say faster mem clock speeds would give you better performace then tighter timings?? whats the point getting that kind of dam expensive mem if your not going to clock it at all?

The mem it made for clocking, thats why its so expensive. Im on 253 at 2.5-3-3-7 1cmd. 503mhz in total, and your on 414mhz at in total. Just up the volt by 0.1v to the mem, lossen the timings and 250+ here you come..lol

Running the Tras at 2ns gives me better performance that at 3ns with the higher freq. Im using an OCZ specific bios at the min though so once i get one more orientated for this ram il have another play.

This ram isnt built for high speeds, but for low latencies (hence the LL), is was expensive because at the time it was the only cas2 memory available. Plus it has cool flashy lights!

With A64s tighter timings are more benificial that bandwith, in almost every application. No point in recieving huge amounts of data if its 3ns too late

Also withe the o/c on my cpu, i only have the choice of 207mhz or 225mhz, and the 207 is better for me
