Wrong, the "CPU-Z" to round up.
There are not "1.213 V" but "1.2125 V"

You did not ".002 V"too little, they are ".0025 V" too little. (only measured at X9000)

And because you want it so, here is the accurate calculation of the same processor relative to a maximum clock with minimal tension. Happy with your cross multiplication. (nothing else I write all the time)

The T9300 is stable at 2,6933 Ghz @ 1.0375V. So figure I do a bit of cross multiplication...

2.6933Ghz...3.298Ghz
-------x----------
1.0375V....... x

Solve for x: (3.298ghz x 1.0375V)/2.6993Ghz = 1.2676V required for 3.298Ghz

You are very much lower by .0551v @ 1.2125v.

Anyway, I wish it remains stable, even if my calculations predict otherwise

Perhaps it's not exactly a linear relationship with Volts/Ghz. I suspect it might be a flattening upward voltage curve as you go higher in Ghz.

Been running Intel burn test on one HDX for about an hour. Passed each test.

Will test the other one for that length of time tomorrow.

i think the normal temps should be in the oc temps column, but no you didnt miss anything

Thanks 2.0™ Yes opps sorry I did mean Shirley fu lol, yeah I get it with the ram due to you guys information its just locating the ram for a decent price and when I did find it (Elle's Post) was not able to be shipped!!

Well any decent links for the X9000 would be good otherwise its back to ebay again, I already have found the ram Here but I dont know if its any good as I have asked the question and they cannot give me model number or make!!

Oh well the hunt goes on lol

thanks

8GB G.Skill in the UK here, but you'll pay a premium.
Don't be afraid of buying from the states, it'll take a little longer and you'll pay VAT on the purchase but the saving cancels that out.

As for the X9000, unfortunately you're looking at over £240 for a used one. I paid around £250 delivered for mine from Shirley Fu last July. I've got to admit though, it's a nice lift in performance once throttlestopped.
Haven't you thought about saving a shed load by following 2.0 and overclocking your current GPU?

PLL TME-UNLOCK FRONT SIDE BUS/CPU OVERCLOCK:

TME unlock of PLL ICS 9LPRS501PGLF

What you possibly stand to gain:

Installed Processor	Stock Speed	FSB O/C'd to 245Mhz	w/ Dual IDA Enabled
T9500	2.6 GHz @ 13x3.2 Ghz @ 13x	3.4 Ghz @ 14x
T9300	2.5 Ghz @ 12.5x3.06 Ghz @ 12.5x	3.3 Ghz @ 13.5x
T8400	2.4 Ghz @ 12x2.94 Ghz @ 12x	3.18 Ghz @ 13x
T8100	2.1Ghz @ 10.5x2.57 Ghz @ 10.5x	2.82 Ghz @ 11.5x

X=CPU max multiplier.

Very nice!
However, a small error. T8400 does not exist! You mean the T8300.

Please change it yet!

It would be wise to save this page in MHTML or some format that keeps it whole with pictures in the event the photobucket account used to store these pictures used in this guide goes over monthly view limit or get disabled. In that unfortunate event, the pictures would be replaced with placeholders.

I have saved so many different versions of your page (only post #2296). (original and translation)
If you're doing something lost, I have backed it.

If TME is unlocked, then you're ready to overclock.
At this point, take the battery out. (You'll thank me later)
You have to overclock in increments. You can't just jump to max. System will hard freeze or hard crash.

Increments that worked:
209.3 Mhz, 218.1 Mhz, 226.9 Mhz, 236.1 Mhz, 244.9mhz,
213.x Mhz ,223.x Mhz, 233.x Mhz ,245.x Mhz
But your CPU may need other intervals. You have to experiment.

Open up CPUz. (To watch the CPU frequency increase).

Now slide the top slider in SetFSB over to 209.1mhz. Then hit SET FSB]

Even if "SetFSB" not so important, this value (in red) will not be same in both cases!?


More questions: I had warned you before!

You say the "HDX" works even without the "FSB OC"with "RAM 400MHz Cas 6 only. (after flashing RAM)

1. Could you see a power change? For example, in wPrime? (important no OC!)

2. And you have flashed two modules at once? Or consecutively?
Excuse my ignorance, I have not yet dealt with it.

3. Do you see problems in the reflash?

4. What you classify the risk?
I'm worried. I only have 2x4GB modules. (ie, 8GB RAM)
All the smaller modules I've sold. I have only one attempt.
What would you do?

5. What happens if I leave my RAM (DDR2-6400 800mhz) original (4,5,6)? (no flash)

It is absolutely important to flash the RAM is wanting to do significant overlocking. WIthout it you may only see a 230Mhz BCLK OC for example. You may want to do your test OC by flashing and using only 1 of our RAM modules. That way you could always boot with the other RAM module, hotplug it and flash it back to it's original spec.

Briefly. Your system boots with a 200Mhz BCLK and runs RAM at 333Mhz 5-5-5-18, so is 3:5 ratio. When you overclock to 250Mhz the RAM is also overclocked to 417Mhz which will lead to BSODs. The way to compensate is to flash the RAM to have a slower 400Mhz 6-6-6-18 entry as 2.0 details which will work fine a 250Mhz BCLK overclock. RAM tends to have tolerance so that 6-6-6-18 RAM timing may very well be good enough for even a 280-290Mhz BCLK (RAM@467-483Mhz). That is if the rest of the system and CPU allowed it. Consider that if it did that then a dual-IDA T9300@282Mhz would be running at 3.8Ghz Optimistic? Maybe. I believe a T9300@266 (3.6Ghz) should be realistically possible if do the VID4+Vss CPU overvolting pinmod.

More questions: I had warned you before!

1. Could you see a power change? For example, in wPrime? (important no OC!)

None I could notice. More or less the same scores in the same range.

2. And you have flashed two modules at once? Or consecutively?
Excuse my ignorance, I have not yet dealt with it.

Consecutively. You can only do one at a time with SPDTool. But you can back up your RAM's BIOS before starting. You can restore your RAm CAS tables at a later date.

3. Do you see problems in the reflash?

No. Just remember to "fix checksum" before flashing.

4. What you classify the risk?
I'm worried. I only have 2x4GB modules. (ie, 8GB RAM)
All the smaller modules I've sold. I have only one attempt.
What would you do?

5. What happens if I leave my RAM (DDR2-6400 800mhz) original (4,5,6)? (no flash)

The risk is low. You can recover a mistake by flashing back original RAM BIOS back to the RAM. Only do 1 at a time.

However, if you don't change to CAS 6 only, the HDX will run CAS 5 @ 667Mhz DDR2. (333.33Mhz x DDR2)

FSB to RAM ratio is 3:5.

RAM will run too fast!

200Mhz FSB x 5/3= 333mhz RAM speed. (Good)
220Mhz FSB x 5/3= 367Mhz RAM speed. (OK + 10% faster)
230Mhz FSB x 5/3= 383Mhz RAM speed. (Woah! + 15% faster)
240Mhz FSB x 5/3= 400Mhz RAM speed. (HELP! + 20% faster)

You'll BSOD around +230Mhz FSB unless your RAM is tolerant. You would have to experiment to find out.

But if you use 400Mhz RAM at CAS 6 only, 240mhz is no problem since RAM speed = FSB Speed in Mhz. (240Mhz x 5/3= 400Mhz RAM speed).

250Mhz x 5/3 = 416Mhz. For 400Mhz CAS6 only RAM, that's only 4% faster.
260Mhz x 5/3= 433mhz. That's only ~8% faster.
265Mhz x 5/3= 441mhz. That's only ~ 10% faster.

And that is why you need to use PC-2 6400 ram 2 CAS 6(400mhz) only. without it, you limit your overclock.

And if CPU had more voltage, it would be stable above 245MHz.

These are excellent questions I will include in the guide!

Edit: LOL, Nando beat me to it.

Topic change.

Edit: LOL, Nando beat me to it.

No, you have completed your fantastic. I thank you both very much!
This is great information for me. I could have used this knowledge for a long time, I had never before engaged in "FSB OC" and "OC BCLK.

Your love you both!!!
-----------------------------------------------------------------------
And because of this my next question to you both.

1. What do you think about Flash "to 800 MHz only with CL5-5-5-15 "? Or even to CL4-4-4-12?

In the old German forum, there was the confirmation, the CL4-4-4-12 RAM running on HDX.

The user "xxJJxx" wanted to buy DDR2 800MHz.
(See here #134 and #152)

After installation, he confirmed the function. (see here #157 and here #172)

Unfortunately he has not written, whether it really "800MHz RAM CL4-4-4-12 ". That would mean namely, that would be the RAM in the "HDX" running at 667MHz with CL3-3-2-8.

Here are the individual contributions in English with Google Translator:
#134 / #152 / #157 / #172 / whole German Forum

No matter such as:
Its speed advantage for "WEI" measure was not very large.

2. What do you think?
3. Is it worth even thinking about it?


Thank you "nando4" and thanks "2.0"!
