To my knowledge this has never been confirmed and was our assumption given the extreme similarities in performance of the good batches of ZX and other CE-6 memory.

well, today i had a closer look on one ZX stick.. ofcourse HS is in the way, but from one side i could clearly see the "-5" at the end..

CE-5?

CE-5?

means nothing more than a 5ns binned part... ;)

Indeed, but why did you actually say that? :) We're talking about the IC here, it's either CE-5 or BE-5.. ;)

we remask the chip already, what you saw is not infineon original mask

even so already.. :rolleyes:

So what exactly is ZX then.. ? Combinations of CE/BE-5s or a certain single IC?

G.Skill tested my memory but they didn't find anything. They used DFI NF4 Ultra-D with a Venice 3000 processor. Anyway, they send me a new kit and this one seems to work properly. No errors in memtest. The whole RMA process was very fast, it took only 2 weeks to obtain a new memory kit.

Today I received another set of 2GBZX from Newegg (for another build). To test them out, I took my first set out and popped these in without changing a setting. Happy to say they passesd memtest, OCCT, pi32m, and a short run of prime at 254 fsb @ 3-3-2-5-1T @ 2.7v. However, they were flakey in 3d gaming. The machine would stutter, sometimes longer than others. I had one instance of a freeze that lasted about 10 seconds, I thought it was dead but just as I was about to reset, it came back to life. Very strange, I've never seen that before. More voltage (2.8v) made things worse.

They are currently running 2.5-3-2-5-1T @ 229 fsb @ 2.7v stutter free. I bought these for $163 AR shipped from Newegg. They will work fine for me, as I could care less about benching, and gaming is supersmooth regardless of the high memory fsb. The tighter timings make up for lost ground there......

I was wondering if you could post down your bios settings for your current setup? As im running more or less the same setup as you and im having a slight stability problems with prime.
Does anyone know what the best tref setting is for the ZX?

Hey Scoobie, have a look here for settings: http://www.xtremesystems.org/forums/...&postcount=267

^I have nearly the exact same settings as you :) Timings get surprisingly tight, I run 234 with 2.5v, 2.5-3-2-6 with awesome secondary timings (BH-5 style) DS/DDS of 8/1, tref 4196. And on top of that, my CPU clocks ~30MHz better than when I was running my UCCC for some reason :confused: Max seemed to be a little under 250 with 3-3-2-6, no 3D problems encountered yet :) Glad to see these are doing better than the 230-240 that I was expecting.

Im currently running the HZ which is solid at 273 1-1 on an Ultra D and just bought a 1G set of there 4400 1GBLE to test as well. Very nice stuff indeed.

What seems to be the best bios for the DFI NF4 SLI-DR mobo when using the ZX memory?

Im running my pc with a 166 divider on the ram. Does this mean that I should only use from the list below the 166mhz values?

Refresh Period (tREF)

---------------------
0388= 100mhz(15.6us)
0516= 133mhz(15.6us)
0648= 166mhz(15.6us)
0780= 200mhz(15.6us)
---------------------
0908= 100mhz(7.8us)
1032= 133mhz(7.8us)
1168= 166mhz(7.8us)
0016= 200mhz(7.8us)
---------------------
1536= 100mhz(3.9us)
2048= 133mhz(3.9us)
2560= 166mhz(3.9us)
3072= 200mhz(3.9us)
---------------------
3684= 100mhz(1.95us)
4196= 133mhz(1.95us)
4708= 166mhz(1.95us)
0128= 200mhz(1.95us)

Which one is best suited for the best stability?

Hey Scoobie, whats worked well for me on the ZX is 3684 or 4196. Mr. G.Skill USA was using 3684 in his testing.

Thanks for tip on 8/1 and 4196, that did allow me to go to 233 fsb stable @ 2.5-3-2-5-1T @ 2.7v....

I also use 3684 for my HZ and I have it running smooth so far at 273 1-1 1T at 2.79v with good active cooling.

Hey, also make sure to try 2.5 or 2.6v, and test all drive strength from 4/1-8/3 (just go to 240 or something and see which lasts longest in memtest for windows). another tref to try is 4708

i am using DFi Ultra-D with bios 704-2bta

the dram drive strength is not called anymore level 7 and so on but instead normal3 , normal4 ....

so which value is the best for the ZX ???

and are there better settings than the one posted by the GS.Tech on the second reply ?

anyone using this bios can help me ?

frequence decreasing ?

Hi,

I know the 2gb zx are not guaranted for more than 200mhz but I don't understand why I have running mine @ 255mhz 2.7v 3-3-2-5 (that was the max) and for 24/7 I have used them at 242mhz 2.6v 3-3-2-5 with 166 divider during three month at least , but since two weeks I suffer of 3d instability at these settings , I never put more than 2.75v because it gave me error in memtest so overvolting can't be .

I have to run them at 233mhz now to keep 3d stability!

Is there any explanation for this big frequence lost?

here is a screenshot of a64 tweaker , I put Level 7 and level 3 for drive strenght and data drive strenght, if I change one setting I'm not able to boot anymore.

unstability at stock speed

Hi,

As I told it last day, I got trouble with my setup and I suspect my ram, as now I can't even run SPI 8M or Prime95 (blend test at priority 10) with stock speed ???

I have tried other bios (a beta one from tony aka bigtoe) but didn't solve the issue.

I will run memtest (windows version) with stock speed and report what.

I have run this setup during three month as in my sig , all was fine (ram was able to hit 255mhz 3d stable), don't understand what's going wrong in my setup.

Any input are welcome, thanks.

Have you tried single sticks to see if one has lost its mind? Are we looking at auto-detected memory timings? Can you get through the built-in Memtest on the mobo? The MAL and RP look .... strange.

r u using SLI-DR EXPERT with 7/3?
that is totally no good i think....
7/x & 8/x are only good for Ultra-D & SLI-DR
for Expert and Venus you need to use 4/x 3/x or even 2/x
but that just my idea
