well i put mine in with my new rig and it was badly unstable, so itook one stick out and it was fine, and passed occt, then i rebooted and put the other stick in and it bsod' before i got into windows...so i gotta rma both of them since its a dual channel kit :(
Why did you guys choose the ZX over the HZ [ guaranteed 250 Mhz ]?
Everyone says the HZ , with UCCC, is the 2 gb kit o get so I was wondering what made you guys choose the ZX
I bought the ZX 2gig kit from the Egg last Monday, received them on Wed. Unstable at stock speed/timings in the rig in my sig. Tried tweaking the timings based on what I read here and other forums with no luck even at stock speed. I RMAed and sent them out on Friday for a refund, not taking a chance on getting another pair with the low quality batch of chips going out recently.
At the time I purchased the ZX, quality was looking good, and I liked the guarenteed tight 2-3-2-5 timings at 200MHZ. The day after I ordered is when G.S Tech hinted that the latest batch weren't quite up to par (bad sign), and other peoples' horror stories about the recent batch around the net started popping up.Quote:

Im running single channel cause i was testing them separately in that case...
I was trying to find out why they cant run anything 3D over 250 3-4-3-8... no matter volts, no matter timings
I got my kit yesterday........works fine at stock speed/timings using a divider, but anything over 200, even at 3-3-3-8 2.7/8v wont even boot windows. I also oredered mine before I read about all the bad kits people were getting but 6 months ago I paid $100 for 2x512mb Kingston Valueram 3-3-3-8............ so getting 2x1GB 2-3-2-5 for under $200 makes me happy :) It seems this last batch definetly isnt the greatest OCing ram though :nono:
I got mine a couple weeks ago and they have proven to be good up to 250 3-3-2-5 2.7v. I know a lot of people have been getting some lemons, but I guess the yield has gotten better since then. And to answer Kaiser_Sose, I bought them for the value and the overclocking potential. HZ timings are guaranteed 250 3-4-4-8 if I'm not mistaken. I can do better timings with my ZX at the same speed, even though they are not rated as such. You take your chances anytime you overclock. It's like asking why we buy $200 Opteron's when we can buy $800 FX's.
I bought my 2g kit from New Egg about a week ago and are working fine at 258mhz with 3-3-6-2 and 2.8v
working fine at 229mhz at 2,5-2-3-5.
Also the settings for memory helped me a lot from techs first post so I got better timings.
So thx.
Are they still bad?
I've just placed a replacment order from a shop who buys them in the usa any day now.
I had a HZ kit before but they wouldn't run at the rated speed on my asus A8N-E :slapass:
rma'ed them but shop had no problem with it :confused:
if the ZX won't OC it sucks :nono:
just want to reach 240-250mhz
well hey guys my zx is being odd... at 10x260 this stuff is 32m stable...
I wanted 9x300 however which gives me a 245mhz mem speed with the 166 divider.
the cpu is good up to 2750, and the mobo has been good and stable at 325 htt for me... but for the life of me i cannot pass 32m at these settings!
is it my asrock mobo? i know this thing isnt great with ram, as it cant run bh-5 at 1t period. but still, this is odd... i might just go for a dfi... lol
Well I was wrong about my kit, at first I couldnt get anything over stock speeds to boot windows.......now it seems I can do 234 2.5-3-2-5 and 255 3-3-3-8 Prime/3D stable. :up: Do you think that they just needed to break in, or is it more likely I just overlooked something the first time around??? :)
I'm going to guess you overlooked something(no offense). That would be one great break in period to go from trouble at stock to those speeds. I think alot of people's overclock troubles come from overlooking one setting, I think we all have missed a setting from time to time.
I don't think ZX needs a break-in. Like aicjofs said above, it's very often that correct setting in BIOS is being overlooked, or AUTO does not always work right for particular setup and in effect, people give up too early. First settings to try are always MAL, RP and Drive Strengths.
Finally got round to testing my ZX set of RAM.
The system it is running consists of an Opteron 144 (CABNE 0540BPMW) running on a DFI RDX200-CFRD motherboard. Everything is air cooled. The processor by a Coolermaster Blue LED 120mm fan mounted on top of a Thermaltake Big Typhoon assembly. The case is a modifed Globalwin 802. It has three intake fans, 120mm and 2 80mm, and 3 outtake fans, all 80mm; although the Enermax Liberty has a 120mm fan in it as well.
Due to the position of the RAM slots on this motherboard the sticks are cooled by the processor fan.
I have been messing with the Opteron and motherboard and the chip craps out at between 2800 and 2900, although suicide screenshot runs are possible at 3000. Motherboard max is 365 HTT. This means I have access to both x9 (default) and x8 multipliers to get to 2800 and above.
I eventually found that the RAM was Memtest stable at 250 (passed the complete test suite overnight with no errors). At 255 the memory would happily pass test 5 all day, but got errors in test 7.
The timings for this stage of testing where the same as used by G.S.Technician in his first post.
Therefore you can add me to the DDR500 3-3-2-5 crowd :toast:
Here are two stable configurations I have with this RAM on a DFI Lanparty UT nF4 SLI DR Expert.
260 at 3-3-2-5 2.8V
265 at 3-3-3-5 2.9V
i finally received mine. It was purchased from Newegg back in the end of November. My friend brought it over to HK since the egg doesn't ship internationally. I also ordered some TeamGroup yesterday in Hong Kong. We'll see how they go...
I just overclock my memory a bit. I can get 220 with latency 2.5-3-2-5
Kampfzerstorer,
PUTALE,
:welcome: to XtremeSystems! :thumbsup:
Love doing that :)
Thanks bud.
thank you. I have been browsing the site, just never posted:).
Just got my ZX kit today.
My best now is 265 3-3-3-5 @ 2,7v pass SPi 32 mb (forgot to take any screenshot)
Here is one of my screenshot

nice score lol...
so im having trouble getting 3D 100% stable.
this stuff will prime allllll night long 32m stable dual prime at 260 with these settings:
http://www.xtremesystems.org/forums/...7&d=1137024370
Thats 260x10 1:1 FYI. fastest ive gotten stable is 265 iirc, i dont need higher then 260 though so i didnt push it...
but gaming at 250 i have to go looser to this:
http://www.xtremesystems.org/forums/...9&d=1137030879
problem is, thats still not stable, after about 2 hours of BF2, it bites the dust.
What else should i change to get this baby going?
I just wanted to bump this seen that I had no reply. Well I tried the memory in my brother's computer with and ASUS A8V mobo and a 3500 Newcastle core, and it worked, the same with the memory in my friends computer also with a 3500 NC and a Gigabyte SLI mobo, and it worked, so obviously it's my CPU (which runs 100% with my 1Gb Mushkin Special) or it's my mobo, so what would it be. Most ppl tell me on other forums that it's my mobo, if so, why does it work on the same mobo on other systems. I mean, the memory does not even want to run stock, much less overclock. It resets the computer sometimes just when I restart..... What BIOS works the best, and what settings and I mean for stock operation now......
PLEASE HELP
