Potential overclocking speed of a Duron 750Mhz Spitfire on an nForce 2 chipset M7NCG 400 mobo with PC266,PC333 DDR.

[Battousai001]

Has anyone here tried overclocking a Duron 750mhz. spitfire? how far have you pushed your cpu's?

Here's my set-up:

- Duron 750Mhz. Spitfire.

- Biostar M7NCG 400 nForce 2 chipset motherboard.

-384MB DDR RAM (1-128MB PC266, 1-256MB PC333 RAM) with a 64MB shared RAM to the integrated GeForce 4 MX GPU.

I just overclocked the cpu to 900Mhz (120mhz fsb X 7.5). and it work fine but in rare instances it crashes when it is about to load windows.

Can I still further overclock this? I noticed that when I tried overcloking it a little bit further (121-122Mhz FSB) it already crashes or restarts. Is it possible for me to increase the voltage? I never tried it before and I just learned that increasing the voltage can further increase overclocked speeds (is this true?) and how far can this Duron (spitfire), M7NCG mobo, DDR 333,266 RAM can go with proper cooling and right voltage?

Regarding the CPU temperature. Before when when it was on the 750Mhz cpu speed the temp. is 50-52 degrees, when I overclocked it noticed that the temperature just increased very very slightly (49-52 degrees). what I did was I lapped the heat sink and then I re-applied a thermal paste then I tried overclocking it to 900Mhz with temperature at 49-52degrees (I noticed that the temperature drops to 45 degress when I returned the speed to normal with a lapped heatsink and a new thermal paste).

Right now Im on 118fsb X 7.5 = 885Mhz cpu speed and is very very stable. Ive read on one of THG's reviews/articles they were able to overclock a Duron 700 types to 950mhz at rock stable performance at a maximum increased voltage of 1.85 volts running on an older motherboard chipset and an SDR PC133 ram only.

Right now my cpu vcore is at 1.65. What do you think? can I still push this duron to its maximum speed of 950mhz?

Is this for a long run, or just for fun?
If it's just for fun, do a crazy voltmod and pump 3+ Voltzes through it, and overclock like mad. Just a big fan is good enough for 15 minutes or so... The record for a Duron Spitfire is 3.2 GHz, I believe. And it exploded, too.

EDIT1: Forgot to add the coolest quote in overclocking history:
Guy 1: Oh no, the AMD!
Guy 2: Yes, it was extreme, too much extreme.
Guy 1: Yes, yes, too much extreme.


EDIT2: FIRE IN THE HOLE! I'll be burning an old Duron 600 in a week or 2, myself. With crazy voltzes and all. I've been scheming for months .

cooooooooooooooooooooooooooooooooool

What HSF are you using?

Try lowering the multiplier to 5.5 and running FSB at 166, the highest "official" bus speed of the chipset. This won't increase your clock much, but it may make the system work faster at the same clock. Also, feel free to hit the CPU up for another .1v or so.

using integrated graphics is going to limit the overclock, most nf2 ultra boards can only do fsb 166 when its on

I retired a system that had a Gigabyte ZXE in it, originally with a T-Bird 1.33 GHz cpu. I never did get a BIOS that would get it to recognize either an Xp 1800 or an XP 2100. It wanted both to be XP 1500's. That's a Via KT-133A chip set, and there was nothing damaged on the board.

So I haven't disposed of it due to the imminent availability of a decent price for DSL from my phone service supplier. I want to put a second NIC in it and run a Linux of some sort or a "*Nix", and use it to firewall my LAN. Never having owned a Duron of any variety, I picked up a Socket A Duron 900 to use (that T-Bird just produces too much heat for a machine I expect to literally ignore most of the time, so I won't put that back in).

But I still have the hsf from the T-Bird, and Gigabyte does allow some speed bumps, although I have no idea what brand and quality the RAM in that one amounts to. Two sticks of 256 MB each 168-pin PC-133 is all I can be sure of (probably a mismatched pair from different makers).

I doubt I would have any need to bump its speed up for this usage, though! Interesting to contemplate, however!

Is that true!?! 3.2ghz duron spitfire? how long did it last? 15mins.?

I think the multiplier is locked, I have tried lowering and inccreasing the multiplier but nothing happened, it stayed at 7.5.

Right now I have increased the voltage to 1.675. But it registers in the hardware monitor of the bios and in the software as 1.73volts. The Duron is rock stable at 900-902Mhz. speed... the fastest I have made so far.... I'll experiment to further increase the speed and voltage up to 1.8 or 1.85 and see if this will still be stable at a maximum of 133Mhz fsb. The temperature right now is still at 50 degrees.

Im not sure though if I can push it further to 166 because one of my DDR RAM is a PC266.

BTW Whats faster? memory running in dual-channel mode (128bit) with 750mhz. cpu speed or memory running at single-channel mode (64bit) at an overclocked speed lets say 950Mhz.? And what is a dual-channel mode/single channel mode? Is that the DDR mode?

 

[Battousai001]

Ive used the stock heatsink of an Athlon XP, and the stock fan of this Duron that runs at 7200RPM. Im wondering why is that faster processor have a fan that runs at lower speeds like 2000-3000 RPM while older processors such as Durons and Athlons has faster fan speed i.e. 6000-7200RPM? Is there a difference if you run a fan that is faster?

 

[Zap]

There may be a difference in heatsink design in regards to required airflow = fan RPM.

For memory speed, generally speaking as long as the RAM is running same speed as the FSB, then single channel doesn't see much of a performance hit if you're using an add-in video card. If you are using onboard video, then more bandwidth = better, so run dual channel as fast as you can.

If multiplier is locked, you can try the "pencil trick" of using a #2 pencil to connect the L1 bridges. Do a Google search and I'm sure you'll find some guides.

With the low amount of L2 cache it would probably benefit from a fsb increase to 166mhz and the memory at 166mhz also.

I would lower the multiplier and try to get at close to 166mhz as possible. Almost 15% in performance right there. Plus whatever mhz increase you can get. Try to do a 6x x 166mhz. That is 1ghz. That would be a noticable 20-25% increase in performance in some apps.

The Athlon got almost 10% increase just going to the faster 133mhz fsb over the 100mhz fsb, and the Athlon has MANY times the amount of cache. So, the Duron could probably increase even alittle more than that. Going from 133mhz to 166mhz might yield another 5% or so. So, 15% increase in performance from the faster fsb and then another 15% increase in real world from the faster mhz. So, a 30% increase in performance is noticable.

Of course, if you are going to even use this system. I am not sure how serious you are

Im just wondering will the CPU heat up or have an increased temperature if ever you use a higher fsb but with the default rated cpu speed? for example if you have a duron with a 750mhz speed with a 100mhzfsb X 7.5 = 750mhz, compared to 750mhz speed with a 166fsb X 4.5 = 750mhz?
