please help with 2800 OC

[Xaggerate]

Okay...after setting up my watercooling and starting to OC...I have found that I can not pull any more mhz out of the system than my 210 x 11 current setup on a NF7-S, Mushkin PC3500 rig..

System voltages are:

Vcore: 1.75
Vdimm: 2.8
chipset: 1.6
AGP: 1.5

If I attempt to raise the FSB any higher, prime will crash in less than one hour..if not...5 minutes....

If I attempt to raise the vcore >1.75 with a higher FSB, it won't pass prime..

If I raise vcore>1.75, chipset to 1.7 and FSB, it won't load windows properly...

And last but not least....if I try to raise the multiplier with ANY or ALL the voltages increased...it won't boot to windows at all...

Please help guys...watercooling should get me more than this...

and I know the CPU was made in week 31....any advice???

need some more info from you. The specs of you system would help a great deal in trying to find a solution to your problem.

So please include your specs and what kind of water cooling you are using:D

[Xaggerate]

Ahhh...alright...I got an answer!!

Specs are:

Athlon XP 2800+ Barton
Abit NF7-S rev 2.0
Mushkin 1 x 512mb PC3500 LVL2 Black
WD 120GB 7200, WD 8GB 7200

Watercooling:

Dtek WW
Dtek VGA waterblock
Dtek chipset waterblock
Eheim 1250
Heater core radiator with 1200mm fan
4 80mm fans
T-line
Artic 5 on all blocks

Please help me...I should be doing a lot more than 2300mhz

[Cutter]

I am sorry to ask again, but what kind of power supply do you have and how powerful is it ie: Watts.


Also how many other divices are running, ie: CDRW/DVD etc....

PSU is very important when it comes to overclocking, but from the looks of what you spent on the watercooling I am sure you did not skimp on the PSU.

Also do you have a cooler on the Southbridge??? this could help also, just take the stock NB and put it on the SB.

But yes you are right you should be getting more than 2300 mhz:(

[Xaggerate]

well...right now I'm just using the 450ww psu that came with the Antec Plusview case that I got recently...this could very well be my problem as I do see the voltage rail dropping to 11.7v or so..

Other than the 2 hard drives and floppy, I'm just running a CDRW and a couple of case fans....

Thanks Cutter...appreciate any input you have...

If I do need a better PSU...and it's 100% my limiter in the rig...do you mind suggesting one as I don't neccessariliy know some good specs to go by that'll be sufficient for my rig...

[Cutter]

I would recommend you throw that PSU you have in the garbage,LOL:D , well I think that is your problem.


I would recommend anything made by Fortron or Sparkle they are great little PSU's and relatively inexpensive, and they are basically the same company.

If you want one that will last ya a while and give you no problems in the future with your current setup go with a 450 or 500 watter.

Also if you have a pretty decent Graphics card IE: 9700 or 9800 or the big ole Nvidia Cards like the 5800-5900 you are going to need a very good PSU like 450 or 500 watts , those Cards use a lot of juice.

That is link to neweggs PSU's

Let me know if the new PSU helps:D

If you get another psu get the forton 530 it has adjustable pot's inside so you have more volts when wanted.

[Xaggerate]

Alright...but before I go throwing my money around...could there be anything else limiting me?....I know the memory is capable of 230ish levels.....

Didn't write the stepping down either :( but I know it came from week 31..so it's unlocked...

[jonspd]

Just a ? whats your temp's @ full load.

[Xaggerate]

with the volts at 1.75, 2.8, 1.6, 1.5 respectively it peaks at 40 on prime95 torture test...at idle...it runs 35

Also...at these numbers...voltage on hardware monitor is:

Vcore 1.74
vdimm 2.83
vio 3.3
+5v 5.0v
+12v (varies) 11.68-11.74
-12v -11.53
-5v -4.89
vsb 4.92
3.3v dual 3.52

??

Thanks Guys...

IMO

Test your rail with a muitlmeter see if you need a new psu. Add some cooling to the board do the vddim and up your 3.3 on your psu and 225+ will be your's. As for the cpu all chips are different some do different #'s the way I do it is find a vcore where the temp's are to high and run the cpu @ a high muilt that way you find you max of the chip then run the chip @ a low muitl and find the max of the board then run the best high muiltxfsb you can.

On your board in order to use 10.5 and 10x @ high fsb you will need to use bios 10 for the board. Some like them some dont the board that is. As for the ram I think your ok there and as for the board well I can assure you it will do more then 210.

Want to go into a bit more detail about this....

I can do the dmm testing easiliy...but what plugs should I test?...where should the numbers be at to be satisfactory or unsatisfactory...

what do you mean by add some cooling to the board? I have the northbridge waterblock...do you mean a heatsink for the southbridge??

what's the vdimm? (I'm sorry..) and how do I go abouts upping my 3.3 on my psu to a higher voltage???

[jonspd]

You can test the molex plug for the 5 and 12 for the 3.3 you will need to test it @ the atx plug. SB cooling on the nf7-s is a must if you want good sound that is and as always one more chip that needs cooled.

If you want to up your 3.3 I can only give you one answer

As for the vddim mod and other usefull info.

@ 42c full load and 1.8 vcore I probable wouldn't go much higher maybe 1.85-1.9 but that would be getting hot I think.

[Xaggerate]

also....within comfortable, and stable limits....what would you call the voltage limits of the processor on this type of setup....I want this thing to last..but I want to push her a lil...:D

[Xaggerate]

No update quite yet...but I'd like some more suggestions....I'm not sure if I said this earlier but I'm running 1:1 ratio....

more suggestions would be awesome guys..

or do I have a dummy chip???

[Xaggerate]

UPDATE:

Voltage readings on a 215 x 11 @ Bios Voltage settings of 1.8, 2.8, 1.6, 1.5 read the following on MBM5 while in prime95 testing...


Low / Average

Vcore: 1.7v / 1.74v
+3.3 3.25v / 3.29v
+5 5.0v / 5.0v
+12 11.49v / 11.70v


I am assuming that with a 1.8v setting in the Bios, that a full 1/10th of a drop would be cause for concern trying to OC a computer past the 2300-2400mhz mark...I also notice that the 12v rail waivers very low and might be the evidence to support my computer crashes at any higher of an OC (guessing the hard drives shut off due to undervoltage??)

PLEASE HELP!!!!

If this is enough evidence to tell me that a new PSU is definitely the solution...I'm gonna drop the dough on the Fortron 530 ASAP..
