What memory out right now will give me the max speed for my current rig plus the new 939 A64s? jonse


any input ASAP would be most appreciated!


Of these 3 can you help me choose?

Mushkin 3500 (http://www.newegg.com/app/ViewProductDesc.asp?description=20-146-294&depa=0)

Corsair 3200 LL (http://www.newegg.com/app/ViewProductDesc.asp?description=20-145-436&depa=0)

OCZ EB PC3200, PC3500, or PC3700. Depends on how much you want to oc HTT 1:1.

What he said. Or more specifically the 3500 or 3700 as it is much faster than the 3200

Well Im looking for the tightest timings.

Then you'll want to look for the OCZ PC3700EB (which has just come out recently) or try to get your hands on BH-5 or BH-6.

why is EB faster then say this:

OCZ 2x 512Mb PC3200 DDR EL Dual Channel Platinum Edition - Timings : 2-2-3-5

Go to www.anandtech.com and read the review. From my best understanding it performs well at stock but not as good as the best but as you incgrase speed and voltage it really shines in bandwith increase even with higher timings. ;) But like I said read the review and you will see the results.

With the EB and that RAM running at the same speed at stock timings, that RAM might edge out the EB by a bit. But, the EB will overclock a lot further on a lot less voltage and you can tighten the timings to something like 3-2-2, which will perform comparably to 2-2-3/2-3-2.

The timing which is shown as a 3 there is RAS-to-CAS Delay (tRCD). This timing has more of an impact on most program's performance then any of the others. OCZ has found, in Micron chips not likely used in the above product, memory that can offer high clock-speeds while maintaining low tRCD/tRP with a slight lapse in CAS Latency (tCL). OCZ's 'EB' series has shown great consistancy for such a product, and it's high clock-speed headroom likely bodes well for Socket 939 CPU's (if they clock similar to Socket 754's).

The capabilities of memory, with regards to timings and clock-speeds, is generally decided by the use of what memory chips.

The above product uses either Winbond CH-5, though I beleive OCZ is weaning itself from these due to dwindled supplies, ProMOS chips (most notably used in OCZ's PC-3700 Gold Rev. 2), or something else that I have not heard about.

Make sure your board has generous Vdimm options...or do a Vmem mod.

Not sure, I think the max is 2.9

How high can we go safe with voltage on these BH-6 chips?

Disregarding any warrenties, all memory can sustain a good amount of voltage, a good amount being up to and over 3.2V, given that there's a good amount transfer of heat by convection. That means there's nothing unduly restricting heat from transfering from the memory to the surrounding air (nothing insulating it) and that there's sufficient cool airflow across the memory.
