Pushing the T9300

Hi all!

Would like a few tips on getting my T9300 over the edge, and I know I would need a voltage mod to do it. So if you have any suggestions, feel free to post them. I want to reach 3.2GHz; I feel that will get me to the 12000 3DMARK06 level. It’s just to satisfy my erg for more, hopefully it will end at that, thanks!

 

Is it an ES ?
Have you OCed the FSB ?
(I guess you have increased the FSB to 240MHz ??)

 

Never heard the T9300 referred to as “ES”?

Hi Andy!

I’ve done everything except adding voltage, and the system tops out at 3.1GHz unstable. I’m thinking I need more voltage. If it’s still unstable at that point, then I’ll just give it up. I would like to take my best shot at 3.2 before I do give up, that’s why maybe someone might post something that will get me where I want to go. I have my work cut out for me anyway, working with PC25300 RAM, but I’ll worry about that later. A BIOS overclcok is not possible with this CPU, just throwing that out there.

 

What happens at 3.1GHz ?

(And are you OCing the FSB ?)

 

At 3.1, the system just stops responding no matter what I do. It will work until I start to open up other windows, then just freeze. Yes, FSB is being overclocked.

 

Have you locked out the increase to the RAM and the GPU ?

If not, its likely that your RAM or GPU is going unstable.

With a 40MHz FSB increase, your RAM must be at ~820MHz (rated is 667MHz). (Monitor with CPU-Z)

GPU must be at a very high frequency as well. (Monitor with RivaTuner, GPU-Z or N-Tune -- whatever )

Try setting the lowest voltage for the highest multiplier (with RMClock - basic undervolting for the highest multiplier). See how much you can drop the VID. Its unlikely that you would need to increase the VID for just a 0.7GHz increase !!

 

I hear what you’re saying Andy, and I have tried both ways. I’m trying to get optimal performance reaching 3.2GHz. I don’t want to get there, and only have a few point more or less in performance, than having it at 3GHz. Each .02 increase, I benchmark the system to insure the performance is increasing, not decreasing. Higher FSB running at 2.8 gives me better performance than lower FSB running at 3.0. I’ve finally managed to change that, but I don’t want to sacrifice too much performance just to reach 3.2.

Any good voltage programs you recommend? I don't want to touch the BIOS yet, would like to do that through software right now.

 

Hey Andy,

Will this set-up basically "Toast" ... Kobe's M570RU!?!?

G!

 

What is higher FSB and lower FSB ?
Which OCing software are you using ?
Can you upload a screenshot of the CPU Page and the Memory Page in CPU-Z, when OCed to 3.0GHz ?

@gonwk: Yes, probably. His RAM and GPU have a good chance of getting fried, since the power consumption will be pushed up alot. Its necessary to monitor the temps....

 

You can try this

Same questions here.

Plus, out or curiousity, what's your PLL?

What's your temperature when you run the T9300 @ 3ghz+?

 

I’m using setFSB.

I do it manually, because I want to increase the performance as I go. I just need good voltage software, and that will get me what I want. It will at least let me know I’m not going any further.

I have a feeling; this baby is going to fry!

My temps are good, so I’m not too worried about that. It’s hard, but somebody has to do it.

 

44c or 45c messing around, so that's pretty good.

 

Could be wrong but no software will allow you to change the voltage. I think your only option will be via pin mod such was the case for Pentium M.

 

That's cool

 

Highest voltage for the T9300 is 1.150V.

And can you upload a sceenshot of CPUz (CPU and Memory Page) Overclocked to 3+ ??

 

I know what the default voltage is, I want to raise it. I guess I could show you everything, but I did lessen an area as I want to keep that secret (performance gain). Even if I leave the bottom lever at default (33.3), the system is only stable up to 3.047. Anything beyond that is a mouse movement away from freezing.

As you can see, temps are not the problem.

nop, it's 1.25v just like my T2500

At what frequency is the memory functioning.
You won't be able to increase the voltage without a pin-mod, they are hard-coded into the chip.
What PLL does your motherboard have ? Did you check the motherboard ?
Try some other software, to monitor the GPU frequencies (something like Rivatuner) - which indicates the active frequencies.

I guess he has the OEM version of the T9300 (SLAPV).
I was looking at the VID range of the Boxed version (SLAQG).

 

OK for the Vcore

PLL is in the attached picture

 

Yeah, I saw that.
I just wanted to know if it is the same PLL as on the motherboard.
His motherboard could have another 9LPRxxx PLL, and is partially getting overclocked by the above PLL.

EDIT: I just saw the DDR frequency. 480MHz (DDR2-960) for a PC2-5300 module. That's overkill.

 

I was not able to test this myself, but I thought if you could overclock a bit with a PLL (even if different from the one in the laptop's mobo) you can go up all the way until you reach the limits of the other componants in the system: CPU, RAM, GPU...
Right?

I'm trying to understand why you're so keen to confirm the PLL.

 

I even take it up a notch to 989.3 when gaming. I'm going to fry my baby "Can you smell what the Rock is cooking”?

 

During the overclock, if the system bus hits the wrong string/value - *boom* (I mean crash).

I could OC my FSB with 3 different PLLs. I never went over 166MHz.
But when I found the software with the support for my PLL, I was able to OC to 200MHz easily. (With a Celeron M 420)

I just wanted to confirm if the OP had found the correct PLL by Hit & Trial or not.
It could be one of the causes, but an unstable GPU normally corrupts the screen display, and unstable RAM sometimes gives a BSOD.

 

I see.

I'm not interested in overclock but in underclocking as you did with your Acer 3680.

Tell me Andy: Where is your PLL located? near the CPU socket but in the opposite side of your mobo?

 

Yes thats right. On the upper side of the mobo (keyboard side).

You know what Andy, that's a good idea.

Since this has to be the easiest computer to work on, I'll just open my bottom panel and have a look. If I do find it's not the correct PLL I'm using, then 3.2 might be possible anyway. Nice tip bro!

 

I believe the PLL will be on the upper side of the mobo.
It is an IC connected to the north bridge, so it will be near the CPU/Fan, but on the upper (keyboard) side of the mobo.
You'll have to remove the bezel (Power Button etc), keyboard, LCD, upper casing and then look for the PLL.

 

I’ve wanted to disassemble the unit anyway, plus I want to take pictures of everything. I doubt if I’ll do that tonight, but tomorrow when I get home might be perfect, depending on how I feel.

 

Thanks for the photo Andy.

For the link I'e seen it few times before. I problem is they say that you could fine the PLL by locating the crystal, but I've never seen a crystal on a laptop mobo and I've seen quite few mobos.

the problem on my laptop gateway MX3101 / MT3705 is that most of the mobo is covered with a black layer of plastic. This plastic is glued to the mobo and I don't want to damage it by removing it. So i don't think I will know what's the PLL n m laptops is anytime soon.

P.S.
I tried all the ones listed in setFSB and CPUCool and not wanted to work, and those that worked made my laptop freeze.

 

After reading the pages of Audigy's thread, I'm sure I have the right PLL.

The funny thing is…I just realized the thread was actually about his automatic overclocking tool. DUH! I thought it was just about setFSB, boy is I really dumb.

Anyway, I think the only steps for me to further my goal are to invest in some good 800 DDR2 RAM. If it can handle 1000 FSB, that will get me what I need from the CPU which is 3.1 – 3.2.

So which RAM (make/model) should I opt for? My goal here is to get the best at a decent price, so let’s try and keep it at $50?

 

You can check out OCZ/G.Skill's 4GB DDR2-800 Kit. (Newegg)

 

Thanks for the tip Andy!

I’m just going to ask in the Sager forum if this will actually work. I know about all the down clocking stuff, but there could be some differences that I don’t know about with the Clevo model that might not like this stuff. I’ll let you know when and if I get it, thanks!
