DDR Voltage... Whats your Vdimm?

jconforti · Mar 9, 2003

I have Kingston HyperX PC3500, rated at 7-3-3-Cas 2.0. My ststem specs are in sig.

I was running the DDR at spec in my OCed system at a vdimm of 2.77. I can run it at 3-3-2-Cas 2.0 if I up the vdimm to 2.90. At 2.77, wont pass Prime 95, but at 2.90, it eats Prime 95 all day long.

Question is, most DDR is warranteed up to 2.8, is 2.9 excessive, or will the HyperX handle 2.9 without a problem?

Also, who else runs their ddr at Vdimm higher than 2.8?

2.9 should be fine, the hyperX comes with heat spreaders right?? if so ide say it can handel 2.0v with good case-air flow

Bah, stick it at 2.9. Hell, I've watched some of the better O/C'ers in our hobby run at 3.1 and 3.2vmem consistently. I run my Twinmos at 2.9 all the time...and probably will be doing a vdimm mod in the immediate future.

2.8 (just raised to go to cas2) 2-3-6-3 166fsb
Tonight i am trying for 2-2-5-2. This is with one stick of crucial pc2100 (128mb) and one generic 512 pc2100 stick. not bad!

I'm using TwinMOS PC3200. I have two sticks running at 193MHz fsb with a vdimm sestting of 2.77v (it shows up as 2.7 in MBM5).

I run at 2.9v as well. Just put it at 2.9 and forget about it
