My new CPU for KT7-RAID

Archived from groups: alt.comp.hardware.overclocking.amd (More info?)

Hi guys, i've just bought in eBay an Athlon XP 1700+ with the
following stepping:

AXDA1700DUT3C 9308726260062 JIUHB 0309SPBW

Do you think it will be a good one?
My plan is to cut L3-3 and L3-5 so it gets a 13 multiplier.

Thx.

Should be a winner. test it before you cut though. Should boot at 1100MHz.

I'm posting this msg with the just arrived cpu at 1363Mhz (109x12,5).
Haven't cut L3 bridges yet. I think i'll cut L3-4 and L3-5 so it gets
a 15X multiplier. I think this will be better than cutting L3-3 and
L3-5 because L3-4 and L3-5 are next to each other and there's less
probability of cutting a non desired bridge.

Any other hint on cutting the L3 bridges? How to do it? With a
cutter?...

Thx again.

Very carefully, and you don't have to go very deep. The first one I did I
about gouged through the cpu.

Well, at 2000Mhz Prime95 outputs a round error... but SuperPI
completes perfectly 512K and 1M tests.
At 1900 perfectly stable.

I'm writing this @ 2Ghz.
Having in mind my HSF is right now a Spire 5E34B3 with copper only in
the base... (recommended by AMD up to 1700+) do you think I should get
a new HSF?
BTW, right now the Spire HSF is running with the copper touching
directly the core; i.e., there's no silver adhesive or silver grease
in there. I have both things here... which one should I apply?
Playing games the CPU gets 55º C!

I recall applying the silve grease to my old 800@900 and getting to
950Mhz and cpu temp dropping ~5ºC.

Thx in advance for your comments.

Use the thermal paste, or axle grease, won't make a difference. The
thermal tapes aren't very good. After you put in the interface material,
up vcore from the 1.60v defaulting on that cpu to at least 1.65v and then
try a higher multiplier. I had to go to 1.85v to achiecve the speeds below.

I'm running at 2Ghz, but at 1,85V, and prime95 reports rounding
errors... Could better cooling improve the stability and o/cability?

BTW, does 21X work in KT7-RAID?

Hmmm. I ran 2GHz at 1.60v. A good PSU and a good cooler will help a lot.

Not by default. you can probably gert it using a wire trick, but if you
want 2100MHZ, just use 20x and up the FSB to 105. Using a combo of
multiplier and FSB I think you can reach any speed within reason between
1500MHz and about 2784MHz (24x116).

Well, this is getting better )

Right now, after applying silver grease... i'm at 2000 Mhz @ 1.775V
(haven't tried lower voltage yet) running Prime95 for ~8 minutes and
core temp is 46ºC... Core temp seems much stable than before... and
best of all Prime95 is stable (ie., doesn't report previous rounding
errs).

My PSU is an Aopen FSP300-60GT with a big fan that keeps case temp
low. Doesn't appear to be bad...

I'm gonna let Prime95 run for a while and then i'll try 105x20...

Do you know what's been my main problem with this KT7-R/1700+? The
main problem with this combo is that after unlocking high multipliers
(13X+) the mobo doesn't run the cpu by default at 100x(new default
mult). It does always detect the cpu as a one with a 12ABOVE
multiplier, giving a default speed of 20x100. The problem is when the
cpu doesn't allow running 2000 at 1,5/1,6V (1,6 in my case with a
DUT3C). In this case you won't even be able to enter bios. The only
solution I found for this is to use the old cpu to set the desired
multiplier. So I cannot try to sell my old Tbird 800@900

BTW, Wes, what are the stepping codes of your cpu running at 2400?

Much thanks for your comments. You've avoided us from having to break
the cash (is this expression correct?) to get a decent cpu.

google for 20x100 and see how many times I've told people that's what it
would default to.
BTW, you can change the default vcore to anything you want using the L11
bridges on the cpu, up to 1.85v. Ah, the 1700+ JIUHB stepping is probably
the drawback

http://fab51.com/cpu/barton/athlon-e23.html

Or you can put 1 wire in the socket and get .2v added to the default
vcore. That would give you 1.80v.

AIUHB or AUIHB. It's a 2100+ model. DUT3C also.
