Won't be able to install it till Thursday. Where can I go to check this chip against a database? Would like to know if others have had any success getting it to 3.0. Below is the data from the chip.

ADAFX55DAA5BN
CABYE 0524VPMW
1271814F50089

p.s. As usual Newegg's shipping is lightning fast but...their packaging of cpu's leaves much to be desired.

Your stepping seems good; XS tested one with a similar stepping (It was an FX57 though) and it hit 3.4G at 1.44V...and Passed SuperPi 32M too at those settings...

Mine will be here tomorrow. Will know more then. But prob wont be able to install till Thursday.

Already in the sig tho, excited about a $139 shipped-to-my-door FX55!!

Going for 3ghz myself.
3ghz + 1mb L2 on a single core Athlon= killer gaming CPU

What exactly am I looking for in these numbers?

What part is the stepping and what part is date code?

I thought default voltage for a FX55 was 1.50V.

Default voltage for the 90nm San Diego FX55 is 1.35/1.4V. The older Clawhammer-cored FX-55s used 1.5v, but they have long been discountinued. 3 GHz is probably possible, although I find that after 3 GHz the voltage/MHz ratio increases dramatically even in CPUs with good steppings. I.E. I'm currently stable at 2.8GHz, 1.375v, and I can POST at up to 2.922GHz on stock volts; however, the "wall" comes pretty quickly after 3 GHz, as I need 1.45V to keep my CPU stable at 3 GHz and 1.55V to keep it stable at 3.2 GHz. After that point, there's not much more left in my CPU without the aid of water/phase-change cooling.

Stepping: XXXXX-0000-XXXX
First 5 letters tell info about CPU (cache, etc), second group of 4 is date made (i.e. 0617 is 17th week of 2006), last group tells information about place of manufacture, etc

This link is very helpful in identifying CPU Steppings:

Although the first 5 letters are the venerable CABYE, the production week seems a bit early for a spectacular OC'ing.. If I remember correctly the Opteron frenzy began with around week 40 (0540) CPUs. But it's still an FX and the stock frequency being 2.6GHz, I'd expect no less than 3.0GHz, especially with DFI NF4.

996GT2: Good info and link! Hmm...so 1.55V is the "safe ceiling". If I can also run 2.8 rock solid I'll be happy. If I can get 3.0 to be stable, I'll be "bursting with fruit flavor"! Will be using AC5 and a Zalman h/s. We'll see.

Aluvus: That's the site I was looking for! Haven't used it in years. Slim pickens for this cput but found this. Exact same cpu and m/b but I'm using a Zalman.

ADAFX55DAA5BN 2902 1.55 Epox EP-9NPA+ SLI SLK948U w/Papst 92mm 25501

Maybe I can get to 3.0

lopri: Well I'm not running a DFI but the Epox boards o/c very well also.

I know it's unlocked but what's the highest mutiplier on a FX-55? "13?"

I can still use the Gogar's shortcut for a FX chip, right?

All Athlon 64's are unlocked downward. The FX's are unlocked upward, also. So, the highest you'll be able to go with it is whatever your motherboard can go up to; probably 18x or so.

Cool...didn't realize that. Can you tell I'm an FX noob? So this would be ideal for 2800 if I'm RAM limited?

200 14 x 200 = 2800 1:1, 200, DDR400 = 200 (DDR400) 5 x 200 = 1000 0.0384

Actually, IMO, people who are RAM-limited in their OCing are really the only people who should buy FX's. Of course, that FX you just bought was >$700 3 months ago. For the price you paid, it was well worth it, IMO. And yes, it's obvious that you're a noob, but that's okay. We all were, at some point.

Why do you say that? My lowly A64 3000+ oc'd to 2.5 plays anything I throw at it today without any issues.

He says that because there are 5 games available today that are patched to be able to take advantage of a dual-core.

I disagree also. If you have 2GBs of RAM and a good GPU. A FX55 will run newer games with ease.

CABCE- 3.06Ghz- 1.475V

All I have done so far is bump the voltage 1.475v and set multi to 15. Oh, I did up the htt a tad to 204, but was not able to really see what it can do yet. This was also with a lame Thermaltake HSF, not tried the Freezer Pro or Mach 2 yet.

OMG...What a moron. You can play 5 games faster then someone with a 3Ghz single..WOW!!! We can run circles around you in every other game out there.

You do realize that the FX57 was the fastest single core CPU ever made, right?

Far faster than any single core conroe (which doesnt even exist yet), right?
Jealous that we got a good deal or something? ;)

You also realize there are dual core problems and quirks still, right?

Dual Core Problems


In our gameplay we did come across some problems that we believe are associated with dual core CPUs, games and possibly drivers. There were times in some games, such as F.E.A.R. that we would ?feel? a slowdown in the framerate. It was as if we were moving along smoothly and then out of no where, unexpectedly in situations not typical of bringing the framerate down we would feel a change in the framerate. Now, it wasn?t enough of a drop to bring us below 30 FPS or cause the game to not be playable. It was however a slight annoyance because when you are at a high framerate and the framerate drops, let?s say for example from 80 FPS to 50 or 40 FPS you feel that change in the framerate and it may bother you.


We feel this is a problem with dual core CPUs because we did not experience this problem with the single core 2.8 GHz Prescott or our regular single core FX-55 we test with on a regular basis. This was only felt on the dual core CPUs. We aren?t sure if this is a game problem with the way it interacts with the CPUs or if it is a driver problem as well, all we know is that it happened with the dual core CPUs and it didn?t happen with the single core CPUs.


Another issue which really isn?t a problem is some weird framerate capping in World of Warcraft with dual core CPUs. Head back to page 6 of this evaluation and look at the World of Warcraft graphs. Look at the Pentium 4 2.8 GHz Prescott single core CPU graphs. You can see that the framerate has a maximum that goes well up to 100 FPS. Now look at the dual core CPU graphs. It seems the framerate is being capped at around 65 FPS. This is extremely odd, we verified VSYNC was off, our monitor was at 75 Hz anyways at 1600x1200, yet the framerate seemed to be capped at 65 FPS. This only occurred with the dual core CPUs. It is a weird issue but one that wasn?t detrimental to gameplay since 65 FPS is plenty of performance for smooth gameplay. It was just worth noting because there does seem to be something different going on in World of Warcraft between single and dual core CPUs.

Before you attempt to refute this, let me just say.. I take Brent Justices word.. over yours. Sorry, I think thats fair?

So again, beyond a few games that take advantage of dual core.. you still have the quirks to occasionally run across.. and its pretty tough to beat the fastest single cores ever produced (FX55 and FX57) for gaming.
There are plenty of games that are held back in FPS (such as WoW) that I'd love to bench a 3ghz FX55 vs your rig anyday. ;)
Considering all things, overall for gaming.. single core is still the king.

Maybe not in a year or two.. as Source doesnt utilize dualcores, but today it is.

The FX55 purchase was perfect for a gamer, by the time this chip has ran its course.. ALL games will utilize dual core and all the other quirks will have been worked out. I do want a dual core, but only at that point.
Till then, I'll be shmokin ya!

I ordered one from the newegg deal, too. Arrived today. For whatever reason, UPS forgot to screw up. Are they ill? Anyway...

CABNE 0524TPMW -0047

Seems I'm the only one on the planet with that week/code. If I can't test tonight I'll have to wait until next Wednesday :(

Sure it'll have a strong memory controller and I might take my Geil One TCCD to world record after all. But I'm not so sure about the CPU core itself.

Well...will post and load WinXP at 3.0 but errors immediately on Stress Prime 2004 even at 1.55V. So I backed it down to 2.9 and 1.50V. I thought it was stable at 2.9 because Stress Prime ran fine, but M.S. MP10 wouldn't recognize an inserted music CD. Bumped voltage from 1.50 to 1.55V and MP10 recognized and ripped CD just fine. I've now run Stress Prime 2004 (CPU&RAM stress test) and 3DMark2001 (looping) together for 6 hours without an error. Haven't done any gaming except D2 expansion, and that really doesn?t count.

p.s. Is a CPU (full load 6 hours) temp of 51C acceptable for a FX-55 2.90? Room temp was 77F at the time. Maybe my Arctic Silver 5 needs to cure some.

I'm using Gogar's settings in bold:

Best Choices:
HTT..........CPU......................Memory..................................Hypertransport..........
290 10 x 290 = 2900 2:3, 133, DDR266 = 193.33 (DDR387) 3 x 290 = 870 0.2733
200 14.5 x 200 = 2900 1:1, 200, DDR400 = 193.33 (DDR387) 5 x 200 = 1000 0.2733
232 12.5 x 232 = 2900 5:6, 166, DDR333 = 193.33 (DDR387) 4 x 232 = 928 0.2733
223 13 x 223 = 2899 11:12,183,DDR366 = 193.26 (DDR387) 4 x 223 = 892 0.278

Just got mine today as well. May be a dumb question, but does a cpu only swap out require a format and reinstall of OS?

Heck no!

Just drop it in your 939 m/b and go. Put everything in "Auto". That's it!
