eva, there is no such thing as 1:1 on A64, memory runs based on a CPU divider, not HTT (FSB).
Dividers such as 166, 183, etc... just change the divider that is used based on the CPU speed.
Many times you can optimize your CPU speed, by using a divider, effectively increasing your multiplier (if you imagined the multiplier to be RAM speed x Multi = CPU speed)
Of course if you have an FX chip, then there is no reason to play with dividers :) But for those stuck with a 9x multi, dividers can be a huge improvement...
BTW, for those looking to buy VX, these guys look like they are in stock (ship worldwide as well) if you don't mind paying a little extra:
http://www.microstorm.com/OCZ_1GB_51...id-529218.html
it's out of stock, pretty much EVERYWHERE......
glad i jumped in on it when i did!
Don't worry, unless I get 260+ dual channel 2-2-2-x, I will be selling my 4 pieces or something and look for BH-5 instead. Per price, it's 1:1 seems good but that doesn't take into account of divider unfortunately which is big turn off for me. (even if I get FX).
I've got my VX on a trial base for now, so i'm just waiting a bit to see if there is a solution to this divider problem. My 3000+ is running at 3000mhz 1.6v prime stable for hours .. i was hoping on the vx to use the 166 divider. Let's wait and see.
166 issue update.
We have programmed VX with a TCCD and EB spd and it made no difference...the modules still didn't like 166 mode.
We have a theory as to why but its best we work with bios engineers to see if we can resolve the issue.
So for now we are advising VX is best in 1:1 mode, some will do ok in 166 mode but your not going to see 300+HTT.
I have started asking if bios files can help, as soon as i know more i will post.
so it definetely is some sort of VX compatibility issue, right? hope you guys can fix this with co-op with BIOS engineers.Quote:

I think this would be a good idea. For sure, case modders love the bling effect of gold and silver heatspreaders. But enthusiasts who care more about the bottom-line performance of a component can definitely appreciate a naked stick of RAM. Off the top of my head, the G.Skill modules serve as a fine example.Quote:

Well, you sure about that? 6 sticks tested so far (2 from RMA) and 1 didn't even hit stock speed 2-2-2-x on 3.5v, now I am just toying with one of RMA'd stick that is keep going down to what seems to be stock speed from 240 below. (@ 215 testing right as I write this....)Quote:

I plan to call and RMA again. However, the cost of shipping this memory back and forth are really adding up. So far, amount of money I had to spend on OCZ RMA is adding up close to $30 with memories, etc.
yes sir.... VX is in my day-to-day rig, NF7-S v2, running at DDR433. i've tried memtest on them and it runs just fine. when i had it in MSI, i get errors right after test #1 :confused: and 99% of them at the same address 308.5MB...Quote:

i now recall that this happened BEFORE i removed heatspreaders but AFTER i started playing with memory dividers.... i think i need to look into little bit closer coz it looks like RAM is fine....
EDIT: i just want to repeat that just few days ago i was error-free @ DDR512 and benchmark-stable up to DDR524....
Looks like the same thing that happened to trans am is also happening to you. In the end, I believe he was only able to run at stock speeds.
*interested onlooker - now concerned with his recent order of vx*
well it seems that I'm one of the lucky owners of this VX memory, got it today together with the DDR Booster, I'll be picking up my ASUS A8N-SLI later this day since they held one back for me :toast:
Now my question is has anyone yet tried the VX together with the Booster on the A8N-SLI? I've saved quit a while for this beast and don't want to fry anything (well at least not in the first month :p: )
hmm i wouldn't try it on a board that will be hard to RMA, might want to wait and see what andy says, he trys the booster on a variety of boards.
I think VX is great for FX where you can use high multi and run VX at it's highest stable ceiling, or a single channel setup. But I think if you ran a divider on the VX, you are better off getting some good tccd and running that at high speeds. I've had 2 sets of VX with 3 different cpus and 3 boards. they both max around 240-245. I think opp got really lucky and this is not normal for VX> don't get your hopes up and think you are going to hit 260mhz out of the box with these. IMO you will be extremely lucky to hit 250mhz stable. I'm not trying to stomp anyones buzz, I'm just being realistic and don't want people to commit suicide because they didn't get their VX past 260mhz. As for the divider issue, I coun't get any divider to work on the neo2 no matter what speed, on any bios except the 100 divider out of the bios., I could change dividers 166/133 etc with A64 tweaker and it worked, but would fail to load os when dividers set in the bios. My heatspreaders came off the day I got mine. I think it's a good idea if you have a decent set . They run much much cooler with the spreaders off because air can actually pass between them even using dimm slots 1 and 2. when heatspreaders are on, they end up touching each other generating tons of useless heat. Take it all off.Quote:

Burn in seems real for me... by about 3-6mhz on each stick except the one that is doing 267-2-2-2-8. Wonder if it has to do with heatspreader settling down or something. BTW, whoever keeps saying this memory runs cool even at high volt is smoking something or running it @ stock speed with high volt. It seems like temperature escalates rather quickly when you have over 3.3+v and actually stressing memory. I've seen so far up to 50c on pcb section of memory. with 2 32cfm 80mm fan blowing directly above that area.
PS) I am getting another set sent out from OCZ today. By thursday hopefully I will have some magic clocker. One thing I found out, they pretest memory without heatspreader. Don't want to invalidate warranty yet but when my stick becomes old it might be worth the fun to take out.

Would it not be cheaper to produce VX without heat spreaders? I know some people think RAM cannot be high-performing without heat spreaders, but those kind of n00bs would not be into buying RAM that needs 3.3V to perform. You could call this new heat spreaderless RAM OCZ VX Lite or something. I'd buy some.
All my testing was done inside the case with no fan blowing on them. I can't wait to get these on the Test Bench try some cooling, might get me some extra hertz:D
OPP
I think one of the reasons they use heatspreaders is to help prevent ESD, otherwise they probably would be making them without heatspreaders. Just a guess though, I may be wrong.Quote:

LOL conrad, I was thinking about getting some chrome 20" rims for my case. It's so heavy with all this cooling, I need to be able to roll it around. Maybe adding a few 12" subs and a few LCDs in the near future.....Please MTV...Pimp my ride!Quote:

Conrad, you realise those modules you have are 10x better than mine... either that or your sis has a CPU with one beaut of a mem controller... granted I can't give my modules more than ~3.35vDimm but they max at bout 261 memtest stable. So either your 3.5v burnin really did wonder, you jus got brilliant sticks, or that CPU you got there needs to be sent this way and fast! :)
I think COnrad had so much bad luck in the recent past with hardware that the overclock gods were finally merciful. He simply got some amazing VX.
it could be the burn in , I mean some of the results people get after burning in are amazing
Those that have tried, do you really see much of a gain between 3.3v and 3.5v?
I ask because I can't feed my modules more than ~3.35v and that drops to near 3.3v under load, 3.3vRail is too low.
So, I'm wondering if upping my 3.3vRail is going to net me any benefits? I would jus go do it but voiding warrantee on a PC P&C is not something I'm dying to do.
I hope it does. With 3.3v I can't do anything over 243 let alone 261. More volts better bring me more mhz or these things are out the door. my BH-6 is doing better right now.
We have tested every module that has come back to us and many that were unstable on customers rigs are fine on the test rigs we use.We still swap out though to brand new modules.Quote:

On a side note guys we test to 240 or so 2-2-2 but going by results seen on this thread overall results can be VERY different. I said this before and i feel i must repeat that this is NOT DDR500 ram, we don't test it that high as there are just to many factors involved in getting a solid guarantee at that speed.
There is deffinitly a difference. Better yet, between 3.3V and 3.7V, bigger difference. :DQuote:

Bacchus, I suggest you try to boot with another memory quick before putting these VX one again. I don't quite know what it is but I had similar sympton and disappeared once I put TCCD in for short time and put VX back. Also, 3.51v, the memory approaches around 50c in my setup. booster pumping heat out from mosfet next to memory doesn't help either. Try better cooling real quick to see if that is the culprit.
I think tonys point is that its PC-3200 and doing 2-2-2 at anything remotely near 500 is quite amazing by itself
Keep in mind sucess at overclocking is affected by so many things
for example I have 2 msi socket 939 motherboards in my personal lab , let me show you some results I got with a few pairs of PC-3200 rev 2 plat( max memtest stable speed 25 passes test 5 )
Kit # 1 board # 1 = 281
Kit # 1 board # 2 = 275
Kit #2 board # 1 = 273
Kit #2 board # 2 = 279
As you can see the results make no sense , just one CPU / board /PSU combo likes one pair better that the other
I am sure I could isolate the problem exactly given enough time , but we accept that things like room temp / electrical noise and so on vary.
Our solution to that problem is to build enough overhead into the products that its imposible not to mee the spec ( in this case the spec is 200 2-2-2 @ 3.3 volts )
With that said, I'm buying myself a Zippy PSU for the Holidays. :DQuote:

It beats us a little, except the 12 volt... but not for long
That 3.3vRail is the real clincher for me... 2x512mb @ ridiculous must suck a fair bit of amps from that rail, and once the voltage is raised the amps available would fall... 45amps is jus plain naaasty
So Ryan, no mention on that offer I made you? :p:
If the Zippys are good enough for the top dogs in Japan, it's more than good enough for a frustrated overclocker in California like me. :D
1) Reasonable priced PSU. Bit hard to do but Powerstream 520W is about 15% more expensive in general than when it came out... LOLQuote:

I know it is not for everyone but so is the bigger than 600W PSU. Might as well go all out if you were going overboard anyway.
3) Despite the fact I didn't buy OCZ 600W, I love how your 20+4pin and 4+4pin lines are set up. Keep up the goodies.
4) Read PC&P's claim of how they measure, etc and claim similar act on your end.
5) Maybe another non standard connector with optional multi meter display that displays voltage of selected channel would be nice on this top dog. Easily switchable between 3.3v, 5v, 12v would give us better idea than LED for actual voltage supplied without having to probe too deep :P (Even using standard molex with different marking, etc could do it so people can still use DMM if they wish).
6).... I ran out of thinkings :) Now do I get something if one of my idea is used ? :)
I would like to see all of the above in a new product dubbed the OCZ Powerstream 690.
690W of ultra-clean power with the absolute bare-minimum noise
+3.3V@69A
+5V@69A
+12V@69A
We'll all refer to it as The Big 69er. I'll be willing to cough up $400 for one if you decide to put it out on the market. :slobber:
marketing would love it too!! LOL
no idea what it is with the price of our products rising over time , the weird thing is we dropped the cost to retailers since the products have been released
notes take on the rest of the stuff
Sorry about getting off topic guys
sorry for going on with my "problem" but i finally fixed it.... ufff.. :)
so to summarize all my efforts, i'm back with error free "memtesting" @ DDR512 (as i was few days ago). the problem was voltage.... i'm at 3.45v now and even cranking volts to 3.5v generates errors now....
so, for now i just keep it burning at 3.45v and we'll see if i can squeeze out anything more of those VX :)
Fine wine gets better with age. You've only been sipping from the glass for 4 days. ;)
Here's to hoping you get what you want out of that memory.

Err... Rookie tested my memory with his awesome cooling prowess and steady voltage on dimm and got 270 2-2-2-x on my pair of sticks :) I am going to ask tomorrow exactly what he did when I see him to drop nice goody off (can we say SLI :P)
Do you guys reallly need a 700w+ PSU? How low are you rails using a 500w PSU? I ask because I can't imagine how my 530w Fortorn wouldn't be enough unless I ran some tecs or something.

Not trying to argue with you but Honestly someone like me uses probably a lot more power than most of hardcore benchers would. It is actually quite simple as why. Bling bling fans, multiple HDDS (lot of times multiple raptors), multiple cd/dvd recorder,... you know... whole bunch of junks that doesn't get used for beching purposes (and even a lot of USB peripherals... I never thought I would run out of 4 USB port at back... I am using about 6-7 depening on back and 2 in front occasionally)Quote:

It is scarey trend but anyone with decent UPS, I suggest you test it out to see how much power you might be using... :)
You probably have a good point if people use that much stuff. I wouldn't make that type of rig a big overclocking unit though.
I do have a regualar everyday rig. I run 3x Raptors a, couple of DVD players, 3 fans and a Floppy on it:D
I use a POS 470W Noisetaker
Runs good though, this is the same rig I used to test the VX memory on without any power problems.

Jin, knowing your setup, (read from forum, heard from few other's etc), I suggest at least 1000VA. Use the 700VA for vapochillLS by itself and few oddities such as monitor :)
Even 1000VA if you calculate out will only power about tops 700W as PSU efficiecny on full load typically is around 70%. (you are actually drawing 1000W to cover that 700W)
700VA will only supply most likely 490W tops. Now, that gets real iffy with Vapo, monitor, CPU, etc.
OPP ->
The way I see it, I don't get any freebies like top benchers do. I pay for my stuff. In fact, I am not that heavy bencher at all as I concentrate more on maximum stable overclock for 24x7 use. I spent the money I plan to utilize it. (which I haven't been too much recently with new parts, tweaking, etc :P)
Could be gaming, could be compiling big fat codes, could be analyzing data.
Wish I could totally separate benching rig with daily rig but not possible for my budget as I do want really good stuff for my main rig as well :) Now, if I do get free stuff like some of you do, I guess it is not an issue or if I make more money than I do now :)
Most unfortunate of it all is, I enjoy playing game a lot and as you all know, most taxing application on entire system out of all application always happens to be gaming :) So, I must improvise and compromise in many ways. Wish I got some freebies too... or be beta tester for some products. Maybe I should start getting into habit of writing lengthy review of items.
Sounds fatal. Take a rest. :)Quote:
