So that being said - NOW should I at least look at exchanging it for the following (with little to no extra cost to me, at most $10-15).This is an AN-DATA IC on a 6 layer PCB.
The way to decode the dates is thus:
The first two digits are the year produced (05 = 2005, 04 = 2004, etc)
The next two are the week (17 is week 17, which would be late april or early may) produced. The last three are the lot number of the day, which means that yours are fairly recently produced modules.
Unfortunately they're not BH5 or CH5 from Winbond, which is kinda surprising seeing as how inexpensive those are. I suppose on the day that those modules you have were made, those ICs were whatever was available or whatever was least expensive. Value Memory is a tough business and most of the time they use whatever ICs they can get in quantity for a low price. I'd be surprised to see the modules do over 220 at any CAS latency, which isn't really shocking considering it's value memory and not overclocking memory.
did you ever decide what to do about the ram? you don't really need ram that can do much, aside from the greater flexibility it allows. 90% of any performance increase is gonna come from a faster cpu, not faster ramLukano said:Well I''ve ordered the new power supply and that gadgety hs/f listed on page 2. If I still have ram issues then, I should still be within my 15 days from NCIX (and I do have a stick of pc2700, or even 2100 - that I can sneak into this machine to tide me over for the rma).
Well I do and I don't. I'm waiting for the new power supply before I run through all of the tests again. I got semi-mismatched results last time (I swear to god I got 330 HTT, but only 2.5ghz and change for CPU) which I'm thinking may be part of the other underlying issues.(cf)Eclipse said:did you ever decide what to do about the ram? you don't really need ram that can do much, aside from the greater flexibility it allows. 90% of any performance increase is gonna come from a faster cpu, not faster ram
however.. flexibility can be a good thing. a very good thing. i think ram purchases should be based off how fast the cpu can do. what's the max of your cpu (unless i'm missing somethign and you don't have it yet) when you drop the ram divider to 133mhz or something?
well i was reading through this thread since im currently ocing the same processor on the same board. (currently @ 285HTT, btw) well i was wondering, isnt 1.5 LDT kinda high considering its at like 1.2 now? The chipset too as i remember default as 1.5 but im not sure.ashmedai said:With that 3000+ you're probably going to have to do LDT 1.5V Chipset 1.8V Startup 1.55V Vcore 1.55V HTT Multi 3x Mem Ratio 133 (improve later)...er I think that's most of it, should get you to 300HT. Just get a proper 24 pin power supply for now, that should help the whole system out and possibly solve all your problems.
Just got shipping confirmation on the new power supply. It'll be shipped overnight, arrive while I'm at work, and I'll throw it in the machine Wednesday morning. Will post results / updates as of then.ashmedai said:LDT 1.4V is recommended for overclocking already if you check RGone's guide for the DFI nF4 UT. 1.5V helps a bit with higher HTTs.
Burn-in is more or less a myth.
thats what i thought at first but then i tried it and i was able to lower my voltage so far and thats always good but of course YMMV.ashmedai said:LDT 1.4V is recommended for overclocking already if you check RGone's guide for the DFI nF4 UT. 1.5V helps a bit with higher HTTs.

I may have spoken too soon. I've just dropped mem down to 3.0 on the nose with +.3v enabled - and it's getting further into the Prim ftt test than the previous settings.fenderltd said:damn even to get 2808 on my venice 3000 I didnt give it 3.2 (ram) lol I say new ram and new PSU maybe then you will be rockin.
The board itself doesn't allow higher than 1.55 straight out of the gate, then +% overtop. I had it at 1.55 + 123% and saw it hit 1.8v and freaked out.fenderltd said:for cpu 1.75 I am water cooled and it will heat up on ya. stock voltage is 1.40 or 1.45 I forget lol!
I've had the same issue. Preset VID & Startup both at 1.50 even - tack on VID Special control at 113% and CPU-Z as well as any other monitor tool will show me at 1.45. I think it's a reporting issue with the bios - but I may be wrong.peterhoang2002 said:ok for some reason, that doesnt really work. theoretically, your SUPPOSE to have very fine tuning capability but it real life (at least for me) it is not so.
for example, theoretically, your suppose to have a few voltage settings/combinations that will allow the actually voltage to fall in between 1.504 and 1.520, right? well in reality, this doesnt not happen for me. with all the combinations there, CPU-Z keeps reporting my voltage as either 1.504 or 1.520. either cpu-z is wrong or the motherboard doesn some rounding.
reason is, i cant stay in windows for long time at 1.504 but i can at 1.520 so i want to lower it down to do some burn-in at that voltage...
New power supply arrived yesterday, and will be installed within the next 20 mins (as soon as I get enough coffee in me). I'll be back with updates shortly.Herulach said:Have you got a multi meter? Sounds to me like your 12V rail is probably drooping a lot, since the way power supplies work is all relative, even a small (11.5V) change in 12V rail can result in something like that happening to your cpu voltage.
Whens the new psu arriving? I personnally think youll see your voltage problems dissapear when you get that in.
You arent mad, it is a ZIF socket, stands for Zero Insertion Force.Lukano said:Grrr... preliminary results not so hot. I've been playing with everything from 280 HTT through 310 HTT. Had it in windows but relatively unstable (and for the life of me I can't recall the settings now) at 300 for a while.
I have tried ram voltages anywhere from 2.40 up to 3.4 (short time only) and every randomized vcore variety I can think of.
RAM timings have been everwhere from CAS 3 with as low as they'll go - even as high as me trying to force CAS 2.
I'm absolutely frigging stumped, and about ready to give up for the morning. I'll keep you updated over the next day or two as I try other options - but with the current ram I don't think I'll see higher than 280 HTT stable.
Ooooh yeah. Marketing lingo sticks in my head as little as I can manage. I was trying to figure out WTF processor went in a Socket ZIF.Herulach said:Zero Insertion Force.
