Overclocking the 1.4GHz Athlon AYHJAR
With my first 1.4 GHz chip extremely deep fried, I was hoping that my next
experience with another 1.4 GHz chip would be more pleasant. MANY thanks goes
out to Mike and the crew from C&P Downtown for RMA'ing my old CPU! Although
it took 5 weeks to get it back, it's still nice to be able to get another
one!
Yes, I've learned my lesson, NO MORE SHIM'S for me! I've also decided to
retire my old Global Win FOP-38 (with the terrible clip) and replaced it with Thermaltake's
Dragon Orb 3. It's more of a sidegrade then an upgrade since the Dragon Orb
isn't much better in terms of cooling but it's got a much more "user friendly"
clip and a copper base.
My old 1.4 GHz chip topped out at around 1.65 GHz, which
wasn't really too bad, I was rather disappointed that it didn't hit 1.7 GHz.
Well, actually, I wanted 1725. Is that too much to ask? A meesly 325 MHz
overclock? After all, being spoiled with my old 1 GHz T-Bird that would do 1.5, I guess
it inflated my expectations a little bit. Anyway, back to the present, I was
brimming with new found hope, but unfortunately this chip let me down too. AYHJAR
with 3rd line Y, and the highest I could get was 1620 MHz!!! What's with all
the rumors going around that the AYHJAR's doing 1.7-1.8 GHz? Was I doing something
wrong? Up'ed the Vcore to 1.85, using a Swiftech MC462-A with my idling temps
around 34 and full load at around 41, what's going on?
While I was very disappointed at my overclocking attempts, the
actual numbers I think are quite impressive.

I was in Boston the whole weekend, so I only had time to do a
few benchmarks... I must say though, Beantown is beautiful!

There simply isn't any compareison here. With the CPU running at 1.63 GHz,
it's easy to see that clock for clock, the Athlon is more powerful. Even at
1.4 GHz, it's a processor that's to be reckoned with!

It's not surprising that at 1.63 GHz and at a 163 MHz
bus, that it's in the lead. However, it seems these days that 3DMark is better
at testing videocards then anything else.

Quake III is really
starting to show it's age. While the scores are very respectable, it's
probably very difficult to differentiate between the two system speeds if
possible at all. It's simply Quake III heaven! While the CPU didn't overclock as
high as I wanted, 1.6 GHz is still quite a feat. Few have hit that speed and the
numbers speak for themselves. It's amazing how well the Thunderbird core has
scaled from 700 MHz to 1400 MHz! However, it looks like the T-Bird is at its end
though, but the successor the "Palomino" aka Athlon 4 has a very bright future
and hopefully they'll continue the T-Bird's tradition of superb performance,
excellent price and remarkable overclockability!
AMD has come a long way since the underpowered K6 line to
it's Slot A Athlon and now Socket A T-Bird CPU's. Even Intel's Pentium 4 has a
hard time catching the Athlon, and the best part is, AMD CPU's are dirt cheap!
Currently, AMD cpu's are SUCH good deals... Less then $200 (Can) for a 1.4 GHz
chip. The closest PentiumIII in that price range is running at a slow 750 MHz, while there's NO Pentium4 anywhere close to that!
