144 @ 2.7? that's crazy overclock.

Forgot to mention running it with only 220w P.S.
Have several 144 and Jetway combo's, and all easily Prime95 at 2700MHz.

RobsTV you got my vote as one of the top budget OC I've seen!

I'm with him. Except I have a whole puter from Karaktu.

I used to have a Sempron 2800+ early Palermo core on a DFI NF3 Lanparty...don't have pics anymore, but I did get that guy up to about 2.7ghz, which was awesome. My thread on it should still be archived if you'd like to look it up.

rig in sig - 144@$150/gigabyte m/b $65

i stopped at 2.5GHz becasue i wanted to run at stock voltage, could have gone higher but i want the machine to throttle/V down when not in use as i bought it to also lower the heat my p4 put out...

Sempy 2500+, E6 core @ 2296MHz (328MHz * 7), default Vcore, $69 total delivered cost for (1) one new OEM processor; (2) one used working Chaintech VNF3-250; (3) one dead VNF3-250 with good BIOS chip, battery, soundcard; and (4) one used working stock AMD S754 heatsink/fan.

But I have to admit that I routinely run it at only 1.8GHz (257MHz * 7).

Perhaps the lowest $/MHz metric for a S754 motherboard/processor/HS&fan combo?

 

[PingSpike]

What are you guys running the hypertransport bus at on your VNF3-250s? Also what chipset voltage are you running?

 

[MiranoPoncho]

Just got my winchester to 2.72. Pos could not do more.

Alright my last two budget chips that clocked high would be a venice 3000+ week 0519 ($117)and an 146 CABYE 0540 FPAW($164).

The 3000+ venice had it running 340x9=3060mhz

http://valid.x86-secret.com/show_oc.php?id=28918

The 146 opteron ran it at 340x10=3400mhz

Sempron 2800 @2.2 GHz. I cant get it to go higher prime stable. Usine a Tforce 6100 Mobo. Maybe I should buy a 3000 venice for my baby.

OMG, 3.4GHz Opteron? What cooling?

 

[thecoolnessrune]

P4 Celeron Northwood core 2.7Ghz @ 3.1Ghz on stock volts. Kinda puny but i could see a difference

 

[dogmir]

i got my sempron 2800+ to 2.712ghz on air....

That's about par for a good Malaysia chip. A friend of mine (was Nowhereman here on Anandtech forums... now nowhere to be found thanks to a permanent lifetime ban from here ) had one that would run for a few minutes at a time at 600MHz - a full 100% overclock, on his Abit BH6 and using a dual fan cooler from some defunct place in Florida (CoolerGeeks or something, sold HSFs that were standard heatsinks with extra fans bolted on, plus were first to market a sandwich cooler for Celerons). His "trick" was to toss the sucker into the freezer, HSF and all. After an hour or so, pop it into the motherboard, turn it on, pump FSB to 133MHz, reboot, enjoy for a few minutes.

AHHHH i loved that cpu. it was my first overclock ever. boosting the 66mhz bus to 100mhz bus did a lot of difference, and i laughed when people that bought the hella more expensive p2 450 started getting all depressed when they realized my system was keeping up in par with theirs

Winnie 3000+ at 2.43 GHz, default voltage, runs around 50 celsius under load passively cooled :thumbsup:

=============================================================
For 1.8GHz setting (7 * 257MHz) - run routinely at these settings:

HT @ 3 x 257 = 771 (slightly underclocked)
Chipset voltage @ default (if memory serves, default is 1.6V)
Memory timings 3-3-3-8; 2.7V (.1V overvolt; may not be necessary)
=============================================================
For 2.2GHz setting (7 * 314MHz) - occasionally run at these settings for 1/2 hour periods:

HT @ 3 x 314 = 942
Chipset voltage @ default
Memory timings 3-3-3-10; 2.7V (.1V overvolt; may not be necessary)
=============================================================
For 2.3GHz setting (7 * 328MHz) - only run briefly at these settings for Sandra runs:

HT @ 3 x 328 = 984
Chipset voltage @ default
Memory timings 3-3-3-10; 2.7V (overclocking memory - .1V overvolt; may well be necessary)
=============================================================

Running Win2K OS. For intense surfing, system has been rock-stable. Have not primed for any significant time at any settings (including stock 1.4GHz).

Using a 60MM fan from a "1 Cool PC" slot video cooler on the heatsink on the nVidia chip. That heatsink doesn't normally get hot but the fan is cheap insurance "just in case" since this is my primary PC. Powering that approximately 3W fan directly from the power supply since I have yet to see published specs for the wattage limits of the VNF3-250's fan headers.

Search all the forums for "VNF3-250" and unfortunately you'll see quite a few reports of dead VNF3-250 motherboards. For that very reason I have purchased a backup board, so perhaps I should have reported my system cost above as $104.

VNF3-250 owners note: I have already had to pilfer the BIOS chip from my non-functional VNF3-250 spare (I own 3 of these boards) to replace the BIOS chip on my day-to-day PC. The corruption of the BIOS chip occurred when I turned the PC off (using the on/off switch on the power supply), at the very end of the memory count during re-boot, after making a BIOS setup change (NOT a flash). The display of my video card's BIOS had finished - that screen had disappeared to be replaced by the boot screen and I thought that the BIOS changes I had made had surely been fully implemented by the time the memory count neared completion (256MB at the time) - wrong! And no, resetting the jumper to clear the BIOS didn't revive it - the BIOS was indeed corrupted.

IMHO, the BIOS code for this board is not well written, nor is the manual for that matter. But I absolutely love the way the board can clock my E6 Sempy so I've been willing to put up with the VNF3-250's shortcomings. At least so far.....

$49 Sempron 3100 130nm at 2457MHz (273x9) with 5:6 memory divider and 1.55Vcore. Corsair DDR400 VS RAM at 2.5-3-3-5-1T. Max CPU temp is 45C with Zalman 7700Cu running at 970 rpm. Prime95 and Memtest stable. 37.7 sec 1M digist Super Pi.

I've reduced the overclock to 1.48Vcore at 2400MHz...38.6 sec Super Pi.

my first OC, Opty 144 (160), Epox 9NPA+Ultra (94), G.Skill DDR500 (100)
got 2.7GHz on 1.55V with my ram at 248MHz, 50% OC

 

[snoturtle]

Easiest OC was a Celeron 2.4 that defaulted to a 533 bus

2.4 to 3.2
