Ok I think I made a mistake. I bought a gig (2X512) of PQI turbo pc3200 because I read that PQI Turbo pc3200 are TCCD module. But, just find out that I have the 2.5-3-3-7 version (they were at a good price and jumped on them). BUT there is also a 2-2-2-5 version!!!! :temper:

I tried a little overclocking on them, but I really don't think I can do 280 fsb with them (will be lucky if I can reach 250 fsb....so what it must be written on the pcb to have the brainpower pcb? Also, do not want to remove heatspreader, because it will void the warranty......
 
Not all TCCD chips are 5-2-2-2 rated...

And as far as I know and read about the PQI...they are all supposed to have the TCCD chips...but the only way to know for sure is taking the spreaders off and seeing if the last letters on the chips state "TCCD"...
 
I do believe that you selected the wrong ones. I know those are not TCCD, but I don't know for sure which chips they use. It might be Mosel.

The only PC3200 from PQI with TCCD are the ones with the 2-2-2-5 timings. There is a big thread on this ram (started by FATAL ENIGMA back in August 2004) that got the whole PQI thing started here. There is also a TCCD based PC4000 from PQI which has the 2.5-3-3-7 timings. Both of these (the PC3200 and the PC4000) have been confirmed to be TCCD by direct conversations with the PQI Marketing Director for Turbo Memory, Eric Liang.

If you expect to do 280 on the 2-2-2-5 PQI, good luck. They ain't gonna do it at 2.5-3-3-7 anyway, not even most GSkill LEs.

Now I did do 290+ on an AI7, but these were the later pair with 0440s or something, and it needed 3.05 volts.

LE's will do 280 7-3-3-2.5...default is 275 7-3-3-2.5 for LE's ;)...and most will run at 5-3-3-2.5 up to around 295FSB with 2.85v...I personally can do up to 289 5-3-4-2.5 at 2.85v 100% stable with my LC's...

But there is no way that any TCCD will run at 5-2-2-2 at 280FSB...the best I seen was 280 at 5-2-2-2 with twinmoss...and even then it took 3.8v to do that...

280 Mhz 2-2-2-5 1T

So how many 2x512 sets of LE have you tried? :) I have tried some, even the heralded 0437 sticks (which I RMAed), as well as the very best P600; that is not easy to do my friend. For one thing, the memory controller of many Winnies are not much good over 277 or so at 2.5-3-3-6 (I've tried six that do 2650-2700 mhz). I only talk benching all four 'Marks, not Sandra screenies.

As someone else mentioned, you sure you don't work for GSkill? (just joking)

The ram needs to be binned. Just because sticks can do 300, 3-4-4-7 at 1T does not mean they can do 275, 2.5-3-3-7, and vice versa. That is why there are LA, LE, LC, etc.

My very best set of ram is late PQI TCCD. This 2x512 set will do 255, 2-3-3-6 at 3.1 volts, 2.5-3-3-6 at 274 at 2.8 volts, and 290+ if I give it 3.05+ volts - on an AI7 to boot! The LE and Vitesta PC600 I had could not do this. Unfortunately 3D is not stable much above 281 on P4 boards (I have not tested A64 on it yet).
 
I just tested a set out a few days ago for a local friend since he swore up and down that they would not do PC4400...I installed them and booted right up at 275/7-3-3-2.5 and was able to run up to 295 at 5-3-3-2.5 with 2.85v...My board craps out after 298 at 1:1 timings...so I couldnt test the max at default settings (7-3-3-2.5)

275/5-3-3-2.5/1T/1:1 Benchmarks (My LC's)

That is not 100% stable...but 5-3-4-2.5 is

And I wish I did work for Skill...I wouldnt be stuck with the LC's...and I heard the same thing when I pimped the 3500 EL's when I first got them...and if OCZ was still located in Indiana...I probably would of been working for them ;)...
 
OK guys, you heard it from Glock: all 2x512 LEs will do 295, 2.5-3-3-5 benching all four 'Marks at 2.85 volts!!! (I can see GSkill cringing in the corner)

Quote me where I said ALL ;)...

And do you happen to know which chips was on your LE's...the ones I tested was the new 440's...my LC's have the 431's...the 431's are not as good as the 440's...the 440's should hit over 300FSB 1T..if the MB and CPU can handle that...
