Highest a 2100+ will go w/o xtra NB cooling?

ffactoryxx · Jul 12, 2003

Baically I have a 2100+ on a epox 8rda+ board with twinmos ch-5 pc3200 (1 stick 512mb), Its running fine at 11x200 7322 right now but want to see how high i can go. My temps under load are 38-40c and idle 34-35c. I have touched both my nb hs and sk-7 cpu hs and both are not hot at all under load( cool). Dont want to push it. vdd is at i think 1.63 in bios. Didnt know if my nb will blow since hs is not getting hot

I would recommed removing the NB sink adding as3 and you will be ok. I dont think you will have any problems as for the NB or motherboard when overclocking but as for the chip it look's like you could still up the vcore alittle and get some more MHZ out of it. But 1st I would set the muiltiplier to like 10 or 9 and see what is the highiest fsb you can run 100% stable you cant check for stability using prime, pcmark, sandra burnin, toast, 3dmark and many other program's. Then after you find the highiest fsb you can run (you might have to up the mem voltage to get there) start upping the muiltiplier .5 @ a time untill you get the chip to its' max speed without running it to hot. I myself dont like temp's over 45c fulll load.

well after 4 hrs of testing 11.5x200, i got illegal sumout errors and 2 rounding errors. What should i do know?
Vdimm is fine at 2.77
Cpu vcore was 1.7 for 11.5 x 200 and default for 11x200

what now

You need to increase your core voltage by around .05v. 1.7v is rather low for 2.3ghz.

emericanchaos · Jul 12, 2003

yeah you need more Vcore. with an XP2100 i wouldn't go higher than 1.9 ish.

c627627 · Jul 12, 2003

Please post all 2100+ code info.

Getting more out of it should be possible. I wouldn't hesitate to go to 1.8V.

My experience with setup that is almost the same as yours is that 1.8 V really allows a bigger push than 1.775 V and below.

You have expensive RAM & that should really help you.

I can do [208] FSB x 11 = 2288 MHz if I take out the PC2100 Cruciial and just use 2 x PC2100 Kingston's.

(Prime95 & 3DMark tested for 24h.)

Note that 6 2 2 2 is much better than 7 3 3 3 so be ready to sacrifice few MHz for 6 2 2 2 memory timings.

Wait a minute,

You knew that ram had a history of problems before you even started last time, is there anything else you want to tell us now before we :burn:

ffactoryxx · Jul 12, 2003

No i found out that the HyperX had problems like 2 months after i got it

I sold it to someone who was able to gert over 200fsb on another board. I just got this twinmos/winbond which does over 200 easy

ffactoryxx · Jul 12, 2003

BTW here are my voltages with my 350watt antec
5v- 4.97
12v- 12.34-12.4
-12v- -13.10
-5v- -5.04

temps under load ar hovering around 43-45c

c627627 · Jul 12, 2003

Your power supply is more than adequate to handle your rig. I wouldn't worry about that at all. More importantly, what's the plan as far as vcore is concerned? How high are you going to be comfortable with?

There's a sizable difference between overclockability of our near identical systems when they're at 1.7 V vs 1.8 V.

Looking forward again to finding out how successful you're going to be and I hope you'll venture into 1.8V territory. You can always go back down but at least there would be a chance to see what your system can do at 1.8 V.

ffactoryxx · Jul 12, 2003

got a pic of you voltages under load??? Any extra nb cooling?

c627627 · Jul 12, 2003

As a matter of fact, funny you should ask, I've done a very detailed power supply test using the same cpu, mobo, heat sink, case and power supply that you have. :bday:

The tests were done at 1.8 V.

Granted it was using software so it's not as accurate but hey, it's exactly what you are looking for, complete with pics of all the details you need:

pick of my voltages
Direguard the cpuz pic. its for 11x200

ffactoryxx · Jul 12, 2003

awsome voltage thread and pic btw way. Why the temp drop near the end? Did you stop prime?

Also my board overvolts i think cause
I set vcore to 1.725 and it reads 1.78. All my vdd is reading 1.623

c627627 · Jul 12, 2003

It's not overvolting, it's how things are. When we talk about V, it's what you raise it to in BIOS.

re temps: Start Prime95 and they go up > While Prime95 is running, you simultaneously start 3DMark > Temps go down a bit

Why? It was discussed in the threads I included for anyone interested.

ffactoryxx · Jul 12, 2003

Well primes been stble i believe for 4 hours. I think that .25 increase helped

c627627 · Jul 12, 2003

You're doing [200] x 11.5 = 2300 @1.725 V & 7 3 2 2, right?

Well ultimately, it's probably a good idea to consider dropping down to 11 instead of 11.5 and test that because if you get to
[208] x 11 = 2288, that wins over [200] x 11.5 = 2300

Also, why 7 3 2 2 instead of 6 2 2 2?

It's been 4 hours, so I'm hoping you'll switch down to 11 soon and start taking that FSB higher.

You know I was convinced from the get go that you can go higher than 208.

You still didn't say how high you're willing to go with V so that may not be an option.

ffactoryxx · Jul 12, 2003

ill take it to 1.8, dont want my nb blowing though. Also on default vcore 11x200 runs like a rock other than a rambom memtest error on on a coldboot run though. disappears after i start the test.

BTW im using twinmos/ch-5 winbond and you need a 3 in cas to ras or vice versa

c627627 · Jul 12, 2003

OK. I'm almost certain you'll do OK with 208 x 11 at 1.8V.

Please explain to those of us who don't know what twinmos/ch-5 winbond is and why it needs to be "at 3 in cas to ras or vice versa."

ffactoryxx · Jul 12, 2003

This is the stuff that the NForce2 boards love. The chips are killer and can easily push 230fsb with nb hs. This stuff uses .13 micron technology and can get higher clocks on looser timings without much vdimm adjustment. This stuff is the best ram for nforce boards at this time. BTW the pcb is made by twinmos and the chips are winbond ch-5 which are also known as samsung killers cause of there superior performance.

thats an old review.

On the "3" setting, i dont know why but thats what every person said they need to be at
