From what I had seen the best results came from week 40 and 43, 45 was fairly good if not best, and 46 was a mixed bag, 48 was pretty bad and so is 50

[Spyrus]

50 is not as bad. All 50 here can do 4050-4100@1.3V.
48 sucks big time. 46 at 80% is good as 50
Older same or better that 46-50

FPO Q745A551 4GHz 1.288v, 4.2Ghz 1.368V

Q746A519 this one i'll get.

[clon22]

I tried 2pcs of week48...
pretty bad.
1pc, 4ghz @ 1.4875v, the other 4ghz @ 1.425v
Managed to find a week 43.
(It was the last pc in the shop)
4ghz @ 1.275v.
Happy user.

FPO Q745A551 4GHz 1.288v, 4.2Ghz 1.368V

Those were exactly mine clocks for 15 hours prime only it was a E8500 and same PFO:P

q745a576 500x8 at 1.25v

[tranceaddict]

Q740A553T 4200MHz @ 1.3625V (BIOS) 12+ hours Orthos stable.

How bout chips to avoid:
Q745A372 - That turd required over 1.36V, and still couldn't do 4Ghz OCCT stable.

Q746A518, by comparison, is doing 4Ghz OCCT at 1.29V. It's actually only been tested up to 4.06 (451FSB), so who knows what the upper limit is at 1.29V.

Q48A142 week 48 also

[Plaicd]

Imho you really need a database with 100's of entries to see if there is any trend that one week is better or worse than another.

As this thread is already demonstrating even some cpu's with the same week code are good and some are bad.

[jas420221]

So...... what place on ebay is showing pictures of the chips and or listing the weeks on it? I havent found any, just somebody listing a ton of them @ $229 w/ 9.99 shipping.

[Mav451]

Speaking of database...yeah I don't think anyone's added anything to mine for a while. But then again, nobody was sure if some of those were just SuperPI OCs. Probably need to redo the database to get rid of those.

[WeStSiDePLaYa]

I have a week 40.

Nothing to write home about. max stable is about 4.4ghz with 1.45.

Volts at 4ghz is like 1.35v.

Think my board could be limiting factor.

Where is the DB? I looked through the threads you created and dont see it in there...

[ThatGuy16]

I have a Q745A567

I'm running it at 4Ghz @ 1.28v. I got it to 4.3ghz @ 1.39v, would need more voltage for stability though.

[Mav451]

Haha it's right in my sig.

[jas420221]

Haha it's right in my sig.

OMFG...

Thanks!

[Plaicd]

I dont get a database when I use that link.
I get a google page asking for a username and password.

[jas420221]

Works for me!

[Mav451]

Oh, yeah you need a Google account to view it or use it. The thing with the Google Docs is that if I haven't added you to the collaborator list, you can only view (not edit). There's unfortunately no "collaborator all" option...cuz frankly, I don't see why I should have to manually add every contributor, if I want the list to be truly open.

Like I said though, this is only data from the first few weeks, in all that hoopla. I should probably start another thread, with no discussion - just #'s. And it'd be much better if the minimum was at least OCCT instead of flaky SuperPI (cuz SuperPI is easily 5-15Mhz off in terms of a stable "gaming" FSB).

air ( TRUE 120 E ) ........( on MSI P35 NEO F ...and waiting foxconn marss )

[jcniest5]

Just got a new Q746A483 to test. The temperare of both cores are stuck at 42/40 (core1/core2) respectively. They never go below that even when idle. They do go up when tortured. Strange...stuck temperature.
