Hi all,

I have 1 x 2gb of:

Corsair XMS3200 Platinum Series
v1.2 - 400mhz Cas 2

Whats the max volts I can put through them without damage???

I have a new DFI Ultra-D that one jumpers 17 changed can push more volts

I'd like to know what a save number is if poss?

Many thanks..!! ;)

edit: says DRAM VOLTAGE CONTROL is 2.60v in BIOS at the mo?

If it is TCCD chips don't put more than 2.9volts through them for 24/7 usage.

How will I know if their TCCD chips mate? Got them from OCuk about 6months ago?!?!

Sounds like 2.9 is the max though! Whats the benifit of pushing it from 2.6 to 2.8 say?

Cheers
 
Actually I'm not sure what chips they are, I thought they were TCCD but I'm not sure at all now. You can take the heat spreader off and see the make of the chips if your upto it. Corsair's website says 2.75v is recommended for that ram if it is 1GB sticks. Do you have 2 x 1GB silver colour ram or black? Your posts says 1 x 2GB.

But with regard to increasing the vdimm. It can help if you having stability issues with your ram when clocking.

Here!!

8th set down!! Testing voltage is 2.75 according to that? Not sure if that means I can go higher than that though?
 
From what I can find your ram is XMS-PC3200C2 Rev 1.x - Infineon BE-5. Whatever it is if it is rated at 2.75v by Corsair then there should be no problem, if needed and effective, raising the vdimm to 2.9v maximum. But like all things you do this at your own risk.

I had 2 x 512MB Corsair XMS4400C25 that was Samsung TCCD and was rated the same as yours, 2.75v, and I had it running at 2.9v for over 1 year.

Hi Michael

Thanks for the info, my pc is running ok but I would like it running higher than 166 and with tighter timing, would more volts assist me in doing that?
Sorry to sound noobish but memory overclocking isn't something I fully understand as yet :D
 
Give me some more details about your PC like current settings and what CPU your using and I'll see what I can do. Does the DFI Ultra D have the 180 divider?

Hi Michael,

At work now but I will do tonight, yes my DFI does have the 180 divider, I have a Toledo 3800+ clocked at 2.8 as per sig ;)

280 x 10
 
IF (Big IF) it is BH5 chips on your ram, then it wont start really performing until after 3.1/3.2v.

But if its not bh5 it'll crash and burn at those volts.

Do I need to take the cover off to find out whats hchips it has then??

Not araid to do so really :)

Because BH-5 rarely passed 250mhz esp at low volts like TCCD would ;)

Basically, if the sticks get to 260/270+ with 2.7/2.8/2.9V then its a very very good possibility its TCCD, as no other chips (apart from variations of TCCD) get that far at 2.5-3-3-7 etc timings.


If it srats falling down at 230mhz @ 2.9V then you might either have some rubbish ram or some BH-5/6.

If you can take the spreaders off youc an try, but personally I would not waste time and test the sticks abilities :)

I may just do that then, my only concern is putting high volts through RAM and causing damage to them :( I'll have a tweak later ;)

Thanks..!
 
CPU mhz are king on the A64's not memory timings and ram mhz. Your at 2.8Ghz already which is a great overclock. Have a read of this from DFI about memory timings and dividers and how little difference it actually makes on the A64 platform:

http://www.dfi-street.com/forum/showthread.php?t=40178

Here is a pivatol quote of what one of the Mod's over there mentions with his proofs in that article

"Memory bandwidth is irrelevant on an A64 because the memory controller is built into the cpu...you can never really give enough memory bandwidth to the processor because it accesses memory directly...there's no Northbridge (memory controller hub) in between them. Memory bandwidth doesn't really mean much in real applications like games and photoshop and this or that. What matters is the cpu Mhz."

Look at some of the scores when running a 1/1, 180 or 166 divider and the scores are practically identical.

Ah very interesting, thanks for pointing that out, TBH I'm happy with my CPU speed and my pc speed in general, I have 2gb of dual RAM and a good graphics card so I'm happy all in all..

Thanks again ;) off to read up

His RAM volts are at 3.00v and 3.40v though........
