3.42ghz, 1.52v actual, and 10 hours into Prime95 with air cooling 
Can't believe it, after so many 'okay' chips, I finally got a good one!

Another 2.4c m0 success!

Nice...My chip a non-M0 stepping did 3.42ghz at default as well....
Here to hoping you get to the 3.6ghz plateau...

Decent....
Just got a 2.4C SL6Z3 (or whatever it is
) from newegg... Hopefully it does 3.3 or so on stock... ( System isn't for me )
I'll update soon.
Once you experience the HT + FSB experience on these chips it would be awhile before you went back.
300FSB is a no go for now. I tried 300mhz FSB @ 1.6v and it wouldn't boot. I then dropped to 285 with 1.52v and started testing. I am going to need to get better Northbridge cooling if I want to seriously attempt 300 FSB. Right now all I have is a passive heatsink on it
definitely...I have an orb style cooler and lapped the NB chip with some AS5....
What mobo are you running???
What mobo are you running???
Actually the IC7 and its undervolting self may require a couple of voltage mods to the board to do 300fsb...I ahve yet to see anyone hit 300fsb that hasn't done the vtt mod especially cause the board gets flaky that high as well as the NB chipset is undervolted and the vdimm ram voltage isnt' up to what it likely needs to cut it...

I don't really game much. More on surfing and spreadsheet stuffs. Occassional divx encoding and programming. HT does not benefit gamers but I heard that it actualyl degrades the performance a little?? Don't flame me. I heard it it, I need clarification.
So, if I were to convert, I would need a new mobo, CPU and RAM. What are the reccomended parts??
In degrading you mean gaming right??? Cause I have tested maybe more HT enabled software then many and I have not seen the so called degradation with HT on and off in the bios....
Divx gets a healthy boost of upwards o 10% with the 5.1 codec from what I hear but in the last year I have moved away from the need to even do any divx encoding..TMPGenc and DVD encoding of my old divx files to someting I can burn on dvd-rs and play on a standalone player gains 22% on average with HT enabled....
Pinnacle version 8.8 has a few % pts better performance in encoding....
DVDshrink3.0beta5 gains quite a bit with HT enabled....
I haven't tested Xvid but I hear it has some benefits as well as some of the wm9 codec encoders....
MOst gaming apps just are not threaded for dual processors whether it be logical or physical.....If you multimedia a bit, office apps, rendering, scientific, and multitask then HT is the chip for you.....
I think the 2.4 or 2.6 is still the sweet spot for sub 200 dollar chips...Couple that with a abit IC7 or Asus i875 P4c800 or even the i865 p4p800 or AI7 and you can have tremendous performance and a chipset that can likely oc up near the 300 mark....The AI7 gives the best vdimm adjustments of the ones I have listed....I would look at any ram pc3500 to pc3700 that has Winbond BH-5 chips and cas 2 to 2.5 at the lowest...

I mean in gaming, I would understand that gaming does not benefit from HT due to the fact that no two threads can be processed at one time without needing a certain data from the other pipeline. I've seen the tests that you've done and I'm certainly impressed wit hthe results.
I'm still trying to gather the cost of the whole upgrade if I were to perform one though. Seems like selling my board, CPu and RAM would only get me an Intel CPU and I would have to fork extra for RAM and mobo.
Here is what you do.....
Get a used 2.4 or 2.6c on the boards for the 160 range or less....
Get a used IS7 or IC& for 95-110 range....
Get what you can afford here in ram...The boards offer many ratios and I have done testing in this area as well and trust me killing yourself in the wallet to run 1:1 or 5:4 when maybe all you have is pc3200 stuff and can only run 3:2 but at much tighter cas 2 timings is almost a wash....
I saw a nice 2x512 set of winbond BH-5 pc3500 434 ultra cas 2 stuff for 180range and many sets of 2x256 and what not in the 110 and baove range....
The selling the items and only getting the cpu may be true but only options of cheaper chip would be the bartons 2500 and frankly it wouldn't me much of an upgrade from your current setup....
I think the athlon64 3000+ would run you about the same as the intel setup if not 40-50 more since the chip runs in the 215 range I believe....

Duvie, I have the IC7-G and am able to hit 300FSB granted the room temp must be below 60f. I too have the tiger 1 but I have a fan on it.

So, you're saying running 1:1 is not really all that important cause I jnow AMD machines benefit alot from 1:1 seeing tha the FSB is only double pumped. Looks like I have got an upgrade coming now.
whenever you can run 1:1 versus 5:4 at the same speed it would be better performance but the real world (non gaming) application are pretty neglible on this....
I run 292fsb but only 3:2 FOR 390ddr but cas 2,7,3,2, with CPC enabled.....It is impossible to run 1;1 at this speed and with only 2.8v of vdimm to give...I could run 5:4 but it takes 480ddr or even better then pc3700 stuff and If I have to run high cas 2.5 or cas 3 it actually can lose out to the 90mhz slower ddr with cas 2....
Check this out!! It was stickied for a bit...
If it limits your oc by 5fsb the ram spee itsn't usually worth it....B

Oh yeah, n00b question. I've always had my RAM on 1:1. How does the ratio thing work?? Sorry to hijack this thread.
Ok for example I will take my 292fsb....
1:1 = 292mhz x 2 for 584ddr
5:4 = 292/5 x 4 = 240mhz x 2 for 480ddr
3:2 = 292/3 x 2 = 195mhz x 2 for 390ddr
Obviously if you can get a i875 chipset it would be better as the GAT or gaming accelerator timings (but they have positive effects in other things then gaming alone) do not disappear if you do not run in 1:1 mode...So like in that example I gave you same speed clock with ddr running 90mhz slower but with cas 2 timings and GAT CPC enabled it actually won quite a few of the benches....
1:1 = 292mhz x 2 for 584ddr
5:4 = 292/5 x 4 = 240mhz x 2 for 480ddr
3:2 = 292/3 x 2 = 195mhz x 2 for 390ddr

Interesting. It's either I'm rusty in maths or the BIOs programmers have set their settings the other way round. i was wound 292/2 x 3.
That's for the informative post Duvie. I'll be looking into an Intel upgrade soon I guess.
5:4 is not to be confused with 4:5....we used to use 4:5 ratios in the days of single channel i845 chipsets and our need to fill the bandwidth hungry beast of the p4 quad pumped fsb....
In that instance with my 533fsb 2.4b I was running 180fsb for 3.24ghz...I used a 4:5 ratio to give me 180/4 x 5 = 225mhz x 2 = 450ddr....
With the abit IC7 those ratios are also still around but generally only come into play if you are running a 533fsb chip or set the NB strap manually to 533fsb or 666fsb in the bios...Under the 800fsb NB strap only options are 1:1, 1:1 spd, 5:4 and 3:2.....in these cases here versus amd (except the newer 400fsb barton mobos) the fsbs are way too high to work with current memory standards and therefore we need raios that can downsize the ram speeds.....The DCDDR help us still feed the bandwidth of the p4 but allow us to oc further without running into physical limitation of current ddr modules..which are 500 to 533mhz ddr but at really horrible cas 3 timings.....

I have a 2.4c that will "only" do 3.06Ghz at 1:1 timings (510Mhz DDR) and 3.2Ghz at 5:4 timings (426Mhz DDR). At 5:4 timings, its definitely not my memory that's holding me back, as it does 510Mhz under 1:1 timings.
So I was thinking it was the CPU holding me back at the 5:4 timings. However, after reading the above, could it be the passive heatsink I have on the northbridge?
