My first overclock...

[akshayt]

1.4volts
HTT=230
10x
4x
5:6
Super Pi 32M ok

1.46volts
HTT=240
10x
4x
5:6
Super Pi 32M ok

1.4volts
HTT=268
9x
3x
Super Pi 1M ok

I have Antec NeoHE 500.

Should I raise the voltage?

2.3 GHz with extra voltage is not a very good overclock on a chip that is stock at 2.0 GHz...maybe you have a bad chip if you need 1.4V just do do 2.3 GHz, both of my friends have gotten 2.5 GHz with that voltage, although their chips won't go much higher.

Also why is the last overclock "1M ok" how come not 32M ok? Unstable?

And why aren't you using Prime 95 to test stability? SuperPi doesn't test the CPU nearly as much as Prime. You should raise VCore and VDimm so that you can pass 12+ hours of Prime95/SuperPi 32M/10 hours of Memtest with no errors, then it's considered relatively stable.

And while you're at it why not show us some pictures of your computer and "sucky" 1900XTX when you are done overclocking?

1) I tried 300X8 with ram @ 266. It did show xp booting screen but for a second showed a blue screen with some text printed and restarted? What was that? Initially ntune button(one of them) was corrupt one time after that boot.

I booted by bringing it back to 200X10.

It was 240mhz with that voltage.

Super Pi 1M means that I haven't tried 32M yet.
Prime takes too much time, didn't have the time yet.

I am on stock cooling at the moment. Do you think the thermal take big typhoon will help a big deal?

Should I try again to see how much can I oc?

Try the 9x multi, my 3200+ winchester wouldn't O/C very well with the 10x. But with the 9x it would do 289x9=2601

 

[akshayt]

To boot with 240X10 I need to bump the voltage to 1.425. How much is safe at stock cooling?
With x9, it shows BSOD even at 270.

What should I do?

 

[cmdrdredd]

if it BSODS when you lower the multiplyer it's your Motherboard limitation or memory not necessarily the CPU.

Try to keep the temps under 65c at full load. If you can do that then any vcore would be ok

 

[Duvie]

I wouldn't go over 1.5v with good cooling so I think 1.45v would be safe with stock cooling as long as you keep the temps under 65c as mentioned above....

1.35v is approx stock (I think they may have some 1.3v ones that come up every now and then....I follow the 10% rule when it come to OCing with air...Therefore 10% of 1.35 is .135v added to 1.35v for 1.485v....



Some board cant handle 300HTT as well....Do you have a chipset voltage option..You may wish to boot that up....

Also raise vdimm up even if you are running relaxed timings and dividers...sometimes the board is the issue with voltages it is supplying...

 

[akshayt]

Asus A8N E
Winchester 3200
2 X 1GB DDR 400 Transcend
Antec NeoHE 500

Stock volts for cpu = 1.4
ram = 2.6 i think, lowest possible

CURRENTLY
Ratio : 5/6
FSB = 240
HTT = 4
CPU volts = 1.425
RAM = 2.6volts
Super PI 1M and 32M tested.
Ran Prime 95 for 2h15 and no errors. Torture test, memory to be used at 1024mb. Temp under full load 54-55 by Super Pi and Prime @ 57C.

I won't be gaming for more than 30-60min at a stretch anyway, do I still need to run prime for 12hrs, I never give that much stress to my hardware anyway.

It doesn't boot with 245 fsb unless I increase the voltage further which at the moment I see no reason to do for a mere 50mhz that too at stock cooling.

If I try with multiplier 9x, it showed a BSOD even at 270.
Will increasing the voltage help here?

Is it possible to get 280-290 X 9 with asus a8n e.
Should I reduce the ram to 266 instead of 333.

Is there anyway of increasing the ram speed manually, like 400 to 410 and so on.

 

[Duvie]

my 3000+ winchester I took it to 1.57v and it ran 2.7ghz, mostly kept it at 2.66ghz w/ 1.54v for over 10months of use(again 10% of 1.4v) ...day to day I have it (still own it: my sons PC) at 2.5ghz stock voltage...Has been living for now 20 months...

I use a simple Venus aftermarket cooler that cost me like 25 bucks...

 

[akshayt]

I am currently on stock cooling and my motherboard doesn't allow more than 1.55volts.

Once I get my thermaltake big typhoon i might try to go higher, do you think it would help?

Most definitely...I didn't really try stock cooling very far but my temps at stock volts at 2.4ghz were higher then my cheapo aftermarket cooler (and trust me that is world better then mine) kept the chip at 2.7ghz with 1.57v.....

I bet you will see load temps barely creep into the 50c range if at all with that vcore range....decent case and room ambient temps and I see loads in the high 40's only...

 

[myocardia]

That heatsink is huge. Unless you've got one of the aftermarket cases, that's more than 8 inches wide, it isn't going to fit. If you end up buying a case, make sure it's got a 120mm fan in front, and one in the back, no matter what heatsink you use.

 

[akshayt]

No way that I will be able to buy a new case.

Which is the best sub 50$ cooling solution for my cpu which doesn't take too much space?

My cabinet i think is around 6-8inches in width.

 

[imported_MSX]

EDIT: Sorry, hit reply in the quick reply box, but I didn't have anything typed...yet it still posted? Weird.

 

[Duvie]

Any of the XP-90's will work just fine...I used a xp-90C on my X2 dual core 4400+ and it ran at 2.57ghz with only 1.47v and stayed under 52c...dual core is harder to cool so XP-90 will do just fine for you...Maybe a Zalman model as well, but I am not as familar with it...

 

[myocardia]

Here's the Thermalright page at newegg: link. I'd personally go for an XP-120, but it's $47, and doesn't come with a fan. The XP-90 won't cool quite as well, but it's $10 cheaper, and isn't anywhere near as deep or wide, which can be a good thing. Also, you might want to think about buying an Arctic Cooling Freezer 64: they not only cool quite well, they're only ~5" tall, and come with a fan. Here's a link to about 100 heatsink reviews for you: link

 

[akshayt]

Is anything wrong with the thermaltake?

Why does my system show a BSOD at 270 X 9 and 300 X 8?
Is it serious?
Should I raise v core and ram voltage or loosen the timings?

Is 3hrs prime test ok if i never game over an hour at a time.
Temps load : 57C normally, initially sometimes was 58C(continuous) and 59C for few secs in breaks


1)Should I try 4-5-5-10 1T and 3-4-4-10 1T?
2)Is 3-5-5-10 1T @ 480 > 3-3-3-8 @ 400?
3)Can all ram modules handle both these frequesncies?

 

[akshayt]

reply please.

 

[akshayt]

is anybody replying?

 

[Duvie]

When you are ocing in earl stages you need to be in "isolation" mode...You should set your ram to divider 133 or less...use very conservative timings....Set HTT multiplier to 3x....want to take these out of the question....

Also stick with the 9x multi...8x multi will run you into board limnits once you get to 300HTT and over....

I would also boost the vagp or chipset voltage a notch if you have it...no go still then boost vcore a notch and vdimm a nocth...dont go 10% with stock cooling if you have something better coming...

 

[akshayt]

Currently stock cooling:
RAM : 2.6volts
CPU : 1.425volts
HTT : 4x
Ratio : 5/6
Multiplier : 10x
FSB : 240

Speed 2400ghz with ram round 400mhz
Tested Super Pi 32M and Prime 95, torture test with some settings changed by me like usage of 1024mb, is that alright?
I ran small FFTs, I ran the test for 8hrs, no errors.

Temp : mostly 57C I think but sometimes 58C and rarely 59C maybe for about a second.

Is this stable enough?

Now I will try if I can find something better with 9x. Else, I may get back to this.

BTW I never did the isolation thing.

 

[akshayt]

RAM : 2.6volts
CPU : 1.4volts
HTT : 3x
Ratio : 5/6
Multiplier : 9x
FSB : 267
Does Super Pi 1M but as soon as I open internet explorer I get a BSOD followed by a restart.
Will increasing the voltage help here?
Do you think that it is worth it becuase even with it it won't be faster than the previous overclock.

First oc timing:
3-3-3-8 1T

Second oc timing:
3-4-4-10 1T

 

[n7]

You need to lower RAM divider most likely.

Use 2/3 not 5/6 (133 instead of 166).


Edit: On your mobo, it's called 266.

Set your RAM divider to 266.

 

[akshayt]

But if I lower my divider to 266, then my cpu will be 2.4, my ram will be around 350 or so and my ram timings will also be crap.
What good is that?

Can't a winchester do :
280 X 9 ?

Will increasing volts help?

 

[n7]

You say you are running your RAM with the 5/6 ratio, as you call it.
That's the 166 divider.

With the settings you described below, that puts your RAM way over its normal DDR400 specs.

Increasing CPU vcore will likely be necessary also, but since you don't seem to want to learn to OC properly (test HTT max, RAM max, & then CPU max), you might as well just drop the divider on your RAM to 133 (266 in your bios).

In case you don't comprehend how dividers work, no, they do not lock speeds @ 266.

It's a math thing.

How to calculate RAM dividers:

(CPU multi x 200) / RAM divider (i.e. 166) = ___(always round this up if not whole number)

CPU multi x HTT / result of initial calculation = actual RAM speed

e.g.
OCed CPU clockspeed / result of the first calculation = actual RAM speed

one full example:

12 x 200 / 166.66 = 14.4 rounded up -> 15

12 x 220 / 15 = 176 aka DDR352
