OCZ using TCC5 chips now...Is this still good?

John, How is the timing with the new TCC5 sticks? Say max overclock at 2.5/3/3/7?

230-240 on my TCC5..

Some better than others most likely..

I think my ram maxes out around 275 once I hit 2T.

Hmmm...personally, I get about 280-282 FSB with those timings. That seems to be the average.

Nebochadnezzar - I've actually heard (and this could be wrong b/c it is hear-say afterall) that TCC5 chips start out as "just about as good" but get better (especially for overclocking) over time as they "burn in."

Oops I meant TCC5. I haven't seen any reviews for the TCC5 Plat Rev 2, but they perform exactly the same so all the benchmarks still apply. The specs are exactly the same.

But if OCZ speed-bins the TCC5, and the "cherry" sticks are marketed as PC-4800, doesn't that mean that the current Platinum PC-3200 Rev-2s are sticks that FAIL to reach PC-4800?

In other words, didn't the "old" (TCCD) Rev-2's include some sticks that overclocked near PC-4800 but the "new" (TCC5) Rev-2's don't have any of those faster sticks, since they're already been binned as PC-4800s?

mines good to about 275 at 2.5-3-3-7.

imo, after reading some of the posts at XS and dfi.street a while ago on this, is most didn't even know until people told them they had tcc5 and not tccd. then it was, "wtf, they screwed me!!!" lol

Ok here goes. I hope this makes sense. Basically, the sticks are first tested at 2-2-2 at 200. If they pass, then they're marked as PC3200 Plat Rev 2. This is the way it's always been. Now, most of the ones that fail, still do high end FSB such as PC4200, PC4800 and so forth. So, most of the PC3200 Plat Rev 2 will still do high FSB. Most people tend to think that they're binned at the high FSB first, but they're not. Does that make sense?

It makes sense in that I understand the algorithm. But what's weird is that one would expect that the sticks that pass the 2-2-2 test (and are marketed as PC-3200 Platinum Rev 2) would have a BETTER chance of reaching, say, PC4800 (at the looser 2.5-4-4 timings) than the sticks that fail the 2-2-2 test.

Which implies that at the considerably lower Rev 2 price, you have a pretty good chance of ending up with better-performing sticks than the more expensive PC-4800 memory. (I realize that there are no guarantees, and the performance of the Rev 2s may well not even reach PC-4200.)

 

[JohnAn2112]

Right. It's the guarantee that people pay for. The PC4800's are guaranteed to hit 300 FSB, while the PC3200 is only guaranteed to run at 200 FSB. It's the same thing that AMD does. The 3000 Venice probably can hit 3500 or 3800 speeds, but it's only guaranteed to run at 1.8GHz.

Hey John,

I sent back you e-mail with the info requested. Let me know if you didnt get it.

I am not going to send back this mem till next week (I need a working comp this weekend) so no hurry on the RMA#, I just wanted to make sure you got my E-Mail.

 

[JohnAn2112]

Nebakanezzar, I received your email. You should have gotten a confirmation email with your RMA number. Let me know if you didn't get it.

This may be an OCZ trade secret (or at least proprietary), but I'll ask anyway:

What percentage of the TCC5 sticks that fail the 2-2-2 test (and thus aren't labeled Platinum Rev 2s) SUCCEED at PC-4800, 2.5-4-4?

 

[JohnAn2112]

I can't tell you exactly. That's something our test department would know and they're seperate from the support department. I would guess probably somewhere along the lines of 70-80% will pass at PC4800. The rest would pass at PC4200 2.5-3-3-8.

 

[msi or epox]

what other manufacturers have come out with tcc5 memory?

 

[Lithan]

Yeah, TCCD got REAL good at the end of it's run. I owned 4 sticks of 512 from two different manufacturers. ALL did 290 2.5-3-3 @ 3.0v or less. And they were Mobo limited. Now that I got my DFI NF4 I regret selling them. I'm hoping TCC5 is just as good so that when it falls into the 125$ range for a gig I can pick one up and run 1:1 again. Oh and ALL my sticks were 3200 2-2-2's. So I can agree that it's highly possible that they are the cherry sticks for at least some manufs. (PDP and PQI I believe were the ones I had.)
