TerraRaptor - Pentium 3 Celeron 566Mhz @ 1496MHz - 1h 10min 53sec 416ms SuperPi - 32M

lol, little Celeron is faster than most Tualatins. Great time!

[ruggero]

wow...vcore?

[TerraRaptor]

Thanks Strunkenbold!

2.3v or smth like that. Done with new tusl2, still testing it. I'm going to bench all my 200pcs of s370 CPUs. The best ones will then be ln2 tested to make some competition for GraduS and others;)

Uff,i had wr cpu-z 566(1514mhz)...if I find a good memory qimonda i will buy also a new tusl2-c for bench.

See you next year for results

I'm doing the same with my s.A CPUs. Currently almost done with categorizing 'em in the excel sheet. Now to the point of selecting best samples per model.

There are additional things like does the cpu unlocks (multiplier, cache, etc), voltage tolerance.

What do you mean? Are there normal CPUs that can be unlocked? For example bigger cache or unlocked multiplier?

 

BTW

I have also a big collection of s370 CPUs. I will never find time to bench those

 

I also want to point that my earlier expiriences with selecting the best ones on air cooling is hopeless. My conclusions after few hours testing was: Exacly the same of 4-5 pieces of the same CPU model??? (for example P3 733 MHz are pretty much the same on air, but on SS cooling differences between pieces was bigger).

many socketA cpu can be unlocked)

I can sell manu qimonda to mans) have some 20pcs

Just to be clear - I'm talking about s.A CPUs.

 

And yes, older CPUs can be multi-unlocked (Palomino, Thunderbird, Duron). Thorton is Barton with one half of L2 disabled and on some samples it can be unlocked and operates stable, which transforms it into full Barton core.

 

Older chips can be unlocked even with pencil, while e.g. Palomino requires e.g. silver conductive paint.

 

Many Thoroughbred and Barton chips are also multi-unlocked, but AMD started to hard-lock them somewhere at the "famous" 39th week of 2003.

For example Semprons (T'bred-B) are locked.

i'm intesting,can you send my a pvt with price for bank?

it's in italian but with google translate it works

 

I remember my applebred@thoroughbred.

[I.nfraR.ed]

Yes, Applebred is Thoroughbred with disabled part of L2 cache, just like Barton -> Thorton.

Of course there's no guarantee it can unlock extra L2 cache and even if it does, it might be unstable. Sometimes that part of the cache is disabled for a reason

I was so shocked that I didn't see you was talking about AMD's socket A cpus

I remember my Duron Applebred -> Athlon attempts. I have quiet not bad experience with modding socket A cpus. I did "L5 sempron mod guide" (in PL language)(I can translate if are there interested ppl)(it doesnt work on NForce (NF1 and NF2) chipsets).

 

ES Intel CPUs are extreme rare. I was trying to buy one... many many times but nobody has one or people didnt know about "ES" or "unlocked" P3/celerons.

 

@Gradus - so quimonda are the best SDRAMs? I binned ~200-300 pieces but it was too few to make me see any dependences between models or manufacturers. I did discovered one - the ones with Printed carbon resistors - are the best (BUT it turned out that SDRAMS without these are also good and I had some of them even better).

 

I also know that probably lot of ppl tried to find a good s370 mobo with DDR1 and I have one (ECS brand P6S5A or something?). Sadly Clockgen is the steppy-one (big steps, ending at 150 or 166 MHz). Anyone compared performance between DDR1 and SDRAM s370 mobos?

[TerraRaptor]

I had experience with chaintech mobo based on Pro266 - it has a little better performance but there were some problems - usb not working after 155mhz, CL2.5 only at high FSB. Also I was able to get to 190mhz only with aircooled NB, 195mhz with SS on NB (but the mount was bad). And these clocks were reachable with custom wpcredit profiles only. Another thing - you will need to make a choice of single-sided winbond carefully. Those working flawlessly on i865/s939 are not the best ones here.

For P6S5AT I was trying to do smth like TurboPLL mod (here is the link http://www.benchit.kz/blogs/blog/terraraptor/859.html) but I had stability issues as realization was baaad.

[gradus]

Imo qimonda not best, but its good. Best i have. maybe 103u better.

Info about Printed carbon resistors is true.

 

Via apollo not very good for fsb. but it faster on 2-2-2-5.
