Just out of curiosity, what would that ram do at 1:1 and 210? Would that speed allow you to use tighter timings? I know the cpu will be slower, but im just curoius.

CPU:DRAM ratio is 1:1; 14 X 210 (420); DRAM at 420MHz DDR.
Wow, that's an instant 10% drop compared to 5:4; 14X255 (510); DRAM at 510MHz DDR.
I have a case of Moosehead here and my wife is in the bin so i have all night!
Cheers!

You're coaching me on overclocking while your world is spinning? Gee, what are friends for, after all! j/k
This BIOS does not have a 4:3 ratio setting for CPU-DRAM. It does though, have 3:2, which what I just tried. Half way through the stress testing, the system dumped memory. Considering that that the RAM was underclocked, this can't be a hardware memory problem. Let me boost the vCore and see what happens.
Thats 3640 megahurtz which i think you can get with slightly higher vcore. Maybe one or 2 steps, thats all. Considering you dont have the sportiest cooler in the world either (no offence), that chip is something else! Any chance getting a Alpha pal again?

Well, I don't think we're going to find the FSB limit on this CPU, at least not with this heatsink/fan.
It appears that thermal limitations are in play now. Still at 3:2 CPU-DRAM, with the vCore jacked all the way up, the system would not pass stress testing.
I've put it back to 5:4; 3.5GHz; 14 X 250; DRAM 400MHz DDR.
When I boost the vcore to try for the higher FSB settings (>250), core temperature starts to reach 59 and 60*C. That when the instability hits. Could be wrong, but I think we've found the end of FSB overclocking, at least for tonight.
Thats still a fantastic chip you have got there. I´m glad for you.

SimGuy, sorry, I didn't write down the CPU series data. Next time I've got the heatsink off, I'll record the information.
So, I take it from your signature that you killed your P4C? Ouch, I had hoped that was symptomatic of the Northwoods, and not the Canterwoods. Maybe the word 'default' (as in clock speed) is in this system's future
I hadn't looked for an overclocker candidate when I was shopping for a P4; I just happened upon this 2.8 through a private deal with a college student. I bought it because he was asking considerably less than Newegg, but I wound up with a hot chip.
Mac, no offense on your remark about my AeroFlow. I selected it as it seemed to have the best cooling to noise ratio in the air cooling category. At 80% fan RPM, it is whisper quiet, and still cools adequately for 3.5GHz.

Thanks for the kind words. That's what I meant by life not being fair. There are so many dyed-in-the-wool overclockers that would search far and wide for such a chip and not find; I went for economy and got the overclocker.
Well, anyway, if you come up with any ideas for the DRAM timings, let me know. I'm game.
Also, I'll probably start overclocking system 2 in a couple weeks. Let's see what dual channel nForce and the 2800+ can do! BTW, it has the same exact DRAM.
Three cheers for Abit. During all this overclocking and tweaking, not once (this session and previous times) did I have to reset the CMOS jumper. That's a first for my overclocking history. I hope the NF7-S is as forgiving and plyable as this IC7.
Leo, you MIGHT have to ditch that ram on the Nforce board though as Amd likes tight timings and fsb of 215 at 1:1. You need 3,2,2 cas 2 to make any use of the Nforce2 actually.
If i where you, the next hardware upgrade would be a couple of sticks of Twinmos with winbond chips on them. If you can find ones that sports the BH5 chip, go for it. The CH5 chips are allright as well but they are better for Intel. They cost the same as the one you have but is WAY better.

At default speeds, the NF7-S/2800+ system is running very well. Perhaps I didn't understand your post.

Yep, put a few too many volts through her (1.75V) at 3.60 GHz (300 MHz FSB x 12). Started up the PC and it refused to POST, playing the dead CPU beep code. I immediately cranked the voltage and clock speed back to normal, but to no avail. What I don't understand is that I had shut the PC down at that voltage & FSB rating the night before and it was working perfectly, other than running a little hot.
Popped the chip out and stuck the old P4 2.26 GHz NorthWood B in and the system fired up like nothing was wrong. The 2.4C made a nice keyring. :bawling:
It was a great chip too.... Week 10 Malaysia L310A781 (one of the best OC'ers).
Good luck with your overclocking adventure! The i875P is a great platform to OC with
//Edit: I should note that I've got another Week 10 Malaysia 2.4C on order, which should be in time early enough this week to still let me have a kick-ass system @ QuakeCon 2003.

SimGuy, don't you buy retail boxed CPUs? Makes life a lot easier...
For example, when I killed one of my TBirds, I cleaned off the residue from the silver-based non-amd approved thermal compound with goo gone and rubbing alcohol, clean off the thermal pad on the retail heatsink so it looks like it's been used, boxed 'em up, sent 'em back to AMD along with a letter saying that while I realize that you're out of stock on the 1.4GHz Thunderbirds and the 1600+, and that a 1500+ is, indeed probably faster than the Thunderbird, I'd really appreciate it if you could replace the TBird with a 1600 or 1700...
I got the box and the guys at AMD sent me a 1700+... ask nicely and you will recieve...
So yea, I almost always buy retail CPUs, just in case...

I've never EVER seen an OEM Pentium 4 processor, so I'm going to be forthright (and WRONG) and say that you can only purchase RETAIL P4's. Geeky has shown me the OEM light!
Yes, it's a retail P4, but it also helps to have connections with the local comp store. Seeing as the CPU is so new that its still within the 30 day return window, I simply took the box back and they ordered me a new one. I know the guy, and he said they just toss the chips in the trash if they don't work, so he told me to keep it
It's fuxed anyways, so I might as well put it to good use
On a lighter note, the new 2.4C came in a little earlier then expected. I'm going to take it easy for a while. Hopefully this Week 10 Malaysia will last a little longer than 10 days

Didn't Intel mandate that all their proc's had to be sold retail when they were going to be sold to the public, or am I just talking out of my ass again?

That's like Microsoft mandating that all their software sold to the public has to be retail boxed. Just 'cause they mandate it doesn't mean it'll happen...
I have an IS7 and 2.4C. On monday I'll be getting some Geil PC3500. Supposedly this is good RAM from the reviews I read. All I'm hoping for is a 900Mhz FSB, but I'll try for 1Ghz. I will post results on Monday when I get the RAM.

RBF,
When you get started on the overclcocking, please start a new thread. This will be fun. I'm definitely not an expert, but would love to watch your progress, as well as provide advice if necessary.
I don't see why your setup can't reach 900FSB, or even 1000FSB. With your mobo-CPU combo, you can, you know, overclock CPU FSB without overclocking the DRAM. I'm using a 5:4 ratio of FSB/DRAM clock. At FSB 250 (1000 quad), my RAM remains in spec at 200MHz. After you determine the FSB limits, then you can put FSB-DRAM at 1:1 and test for system overclock.
Anyway, really looking forward to seeing what the Abit-865 chipset will do!
Leo

Seemed to have worked through a logjam. Not quite sure what I did to improve performance, but I guess it was a combination of the following:
1) completely flushed system of video card drivers and reinstalled - did cure some instabilities
2) removed stock vid card and northbridge HSFs and replaced with oversized heatsinks - passive only, with no fan, but pretty large.
Well, anyway, here is the latest stable overclock:

I believe you should also test how far the cpu goes so that you know it isn´t the chip that stops you.
So, to try the cpu...go 260 and 4:3 so that we kow your ram can handle it.
Cheers!
