ocz value vx.. help me out

[LyNX31]

ok, i dont own a dfi ultra-d yet and by no means am i an expert in overclocking. i am trying to do as much research as i can. let me start off by stating my objectives. i want to overclock a 3200+ venice but im not interested in getting the ultimate overclock outta it.. maybe 2.4-2.5 ghz. i am reading these horror stories about people frying their ram cuz they are pushing 3.2+ volts into them and trying to run them at 2-2-2-5. my goal is to overclock but not spend a whole lot of money on ram.. hence im researching the value vx sticks for now.

http://www.newegg.com/Product/Product.asp?Item=N82E16820227213#DetailSpecs]ocz value vx[/URL]

my question is, if i run the sticks at 2.5-3-3-7 like they are rated and push maybe 3.2 volts or less into them, i can still overclock say using a divider of 166 (5/6) and push my cpu to say for example 250fsb.. correct? maybe its just me but seems like not enough people are using the dividers?

i guess im wondering why these sticks are crashing on some peoples dfi boards(read long thread on dfi-street.com) when they try to push 2-2-2-5 at high voltages at 1:1 ratios. from what i read so far the lower latencies only save u 1-2%??

please advise me.. any help and added information would be appreciated! just looking to build my next system properly.

I think you should be fine keeping the volts at 3.0-3.1 or less. The ram is rated to run 2.5-3-3-7 at 200mhz at default volts (2.6 I think), and only warrantied through OCZ at default volts since they are untested.

(The tested ones are warrantied up to 3.5volts... but cost about 40-50 more)

At 3.0volts, you should be able to hit 2-3-2-8 (or even 2-2-2-8) at 200mhz with no problems. Use a memory divider. But honestly, to be on the safe side, stay at 2.8-2.9volts. You really don't want to fry your ram. I have the gold vx 3200's and currently pumping 3.1volts into them and thinking about backing down. They run quite hot, but I'm not too concerned since they are warrantied up to 3.5volts. OCZ reps recommend a fan blowing directly on the ram 3.2volts or higher.

i can still overclock say using a divider of 166 (5/6) and push my cpu to say for example 250fsb.. correct?

Yep! The difference between running 1:1 vs a divider is a few percentage points.

If you run the sticks at 2.5-3-3-7 with the 166 divider, then you won't need any more than 2.8v. This is the best bet if you don't want to run high voltages. Just set the CPU to run at 250, set the 166 divider, memory timings at 2.5-3-3-7 at 2.8v, then you're all set!

Use 3.2-3.4V for this ram if overclocking.

Always use 2-2-2-5 timmings, if you dont, thats stupid.

Having a fan to blow over them will make sleeping at night a bit easier.

By the way, 3.1V for this ram is nothing, I suggest try 3.3-3.4 if your overclocking, if not, 3.0 should be fine 2-2-2-5 stock.

well the thing is.. even if i do overclock.. it will run near ddr400 speeds still if i run a divider right? so why even go in the 3.2-3.4 range? please clarify.

My Value VX ram would do ~230-240Mhz @ 2-2-2-5 timings with 3.2V. If you're game to run the volts a little higher (read, not too high) than you can get some very decent timings out of the Value VX. Even with 2.9-3.0V you should be able to hit 210-215Mhz @ 2-2-2-5 timings.

OCZ Value 'VX'
if i run the sticks at 2.5-3-3-7 like they are rated and push maybe 3.2 volts or less into them, i can still overclock say using a divider of 166 (5/6) and push my cpu to say for example 250fsb.. correct? maybe its just me but seems like not enough people are using the dividers?

I purchased DFI Ultra-D, and 2x512 OCZ4001024WV3DC-K. I want highest OC using low latency mem. The concept of the Value VX is to 'roll the dice', and hope that you get the performance of a dimm pair costing $50-$100 more. With 2.5,3,3,7 settings and 2.6 vdimm, you should be able to OC your Venice as though you were using any other 'value' ram. Instead, if you want, to run at '2,2,2...', then lay your money down, and roll.

My pair are not matched. I tested them individually, as the pair can not run faster than the slowest dimm. First one will run MemTest stable 3-4 hours 2-2-2-5, 235 MHz, @ 2.9 vdimm. (Goodness!) Second one will NOT run 2-2-2-5 @200MHz, even with 3.2 vdimm. However, I found it will run MemTest stable 2-2-2-11, 200 Mhz @3.0 vdimm. I got what I asked for, low latency, but I did not expect it in this fashion. What other $109 RAM modules will give '222' performance?

Did I roll 'craps' or 'make my number'? I need to test more to answer the question. Plus, there is the option to run 2-3-2, and others.

The people 'frying' their boards or memory are moving board jumpers to enable higher voltage on the Ultra-D. My BIOS limits vdimm at 3.2 without the jumper move, and dimms are HOT at 3.2. I may move jumpers and try up to 3.5v just for test purposes. If you run 3.5, they can fry.

DFI Ultra-D, rev.= unmarked; 510-2 BIOS
Venice @? (still testing), LBBLE, 0517
OCZ Value 2x512 (UTT), 2-2-2-11, 200Mhz, 3.0vdimm
Antec 500w SmartPower 2.0
