Is it worth it to buy OCZ Value VX Winbond Mem?

Trying to figure out which memory to buy without breaking the bank. . .

Have a Epox 9PNA Ultra + Venice 3200. . .

Almost out of money, looking to buy memory that will allow for some good basic overclock.

I've been looking at the OCZ Value Winbond memory based off the Anandtech review, however it looks like the Epox can only do mem voltages from 1.5 to 1.8.

Will this memory be wasted on this mobo? Or will I get the same results from some Crucial Value RAM?

Thanks in advance.
 
I'm pretty sure that the Epox can get up to 3.1 volts, which will bring you to an fsb of around 230-240 with burn in at 2-2-2-6.
 
i think 240 is pushing it with 3.1 volts...

the only board i'd refcommend vx with is the dfi... since it gives you high voltage options...

@hamlet.. i'm pretty sure that board allows voltage higher than 1.8 on mem... i think you're thinking vcore...

ddr2 uses lower voltage for mem not ddr1

I am totally new to this, I am planning to get a 3200+ Venice and i want to overclock it. I hear that 2.7ghz is very achievable. I also understand that A64 processors work better with 2X1GB modules. I will have a DFI Lanparty mobo. Can someone please tell me which ram is optimal for me.
 
Shimmishim or whoever can answer this question -

If the VX is overkill for the Epox board, what kind of results can I expect from Crucial Value? Is there a good value ram that will give me more options than others?
 
Crucial Value is speed-binned Ballistix, so you're taking your chances with that brand. I'm pretty sure Value VX is the way to go, if you're willing to get a DFI board.
 
235-240 at 3.1 isn't pushing it at all. Right now, My twinmos SP BH-5 can do 2-2-2-7 235 at 3.1. I get 0 memtest errors and can run prime95(the one that loads up the ram) all day. You just have to burn your ram in in order for it to get to optimal speeds. IMO the valueVX is def worth it. Tight timings and some rise in fsb with a divider will get you similar performance to TCCD that has loose timings but high fsb.
 
My Corsair Value Select will do 275MHz FSB at 5:6 memory divider. The 5:6 divider amounts to about a 40MHz hit on the CPU core speed. Vdimm is at 2.7V.
 
Im a first timer. U should read the article anandtech wrote that tested value rams
-the Bh5 (2 much v required) and Value did pretty well but i'm wary of using that ocz value with anything other than the dfi's like in the test

-what good TCC5's are out that can oc with 2.8 - 3 vdimm like the epox?
-i have $150 max for ram and was thinking the same as hamlet
-any1 had experience with msi neo 4-f?
 
You just have to burn the ram in. I doubt that the review had time to acutally burn the ram in. You have to keep it on mentest/prime 95 for a few hours(5-10) a day for a week at high voltage. After that, they will respond well to less power. Also another thing ot keep in mind is that using the 5/6 divider with 230 2-2-2-6 ram is pretty good in itself, and performancewise, will compete very well with TCCDs at 280 FSB that have high timings.
 
I have almost the exact system the OP does, with a 3200 venice, 9NPA and OCZ Value VX.

Currently I'm running stable at 240x10 for the CPU, and have the RAM on a 5:6 divider at 2-2-2-7 for 200FSB. I haven't tested anything higher, but I imagine I could probably do the ram at 207 and higher if I can get my CPU OCed to that level. I'm running 3.0v to the RAM right now..

So, I'm no expert, but it definitely seems to be performing well, and I haven't even hit my cap on FSB yet.
 
Running at 5:6 divider is the same as DDR333. You're not going to notice the speed drop with normal PC use. Download SuperPi mod 1.4 (with 3 decimal places) and run the 1M digits test. You will see that the 5:6 memory divider will cost you about 50MHz CPU core speed. Droppy to DRR266 will further reduce the performance by another 50MHz. Remember to run about 10 tests and take the average.

I'm sure other benchmarks will indicate similar performance hit. The sweet spot for memory divider is around DDR333. If you can't raise the FSB by more than 6MHz when dropping from DDR400 to DDR333, then you should stay at the current RAM speed.

My cheap Corsair VS can do 229MHz at 5:6 memory divider. This translates to about 275MHz FSB, which is more than adequate for many AMD CPUs.
 
So what you're saying is that in order to justify going down a divider level, I have to gain more than 50mhz in CPU clock speed? So if going from 166 to 133 allows me to jump from 240 to 250x10, I should do it?
 
The divider will have no effect on the overclock. Its just that if you overclock your memory along with the cpu, you will see a marginal performance boost. Already, it has been proven that overclocking your FSB will not give you a huge performance gain. There was an article on that in ANANDTECH a few days ago.
 
I recently bought a 1GB (2x512) kit from a forum member. Sadly, one of the sticks is bad. The other however is the stick I'm running on now. 1.5.-2-2-5 at 220Mhz 2.9V. I'm running SuperPI in the background now. This memory is great...if it works lol.
 
hacp, this ram isnt the same as your bh-5...it is ch-5

even with my ocz vx that can do 265 @ 3.3v, i can barely do 230 at 3.1

i can even do up to 258 with 3.2v

i've been through a lot of vx...probably at least 8 pairs (all the ch-5 variety)

they need 3.2-3.4 to perform optimally from my experiences

realistically, 220-230 would be the aim for vx value
