Asus P5K Deluxe - Strap Changed @500FSB !

[ChaosMinionX]

With bios 404, my board wont even post with DRAM Static Read enabled

[eva2000]

Am I the only one who actually set the Dram Static Read Control from AUTO to Enabled???
It's EVA2000 who referred this link to us on I4memory and mentioned that there's no negative effect of strap change for 0404 BIOS but yet I still see everyone including EVA2000 setting DRAM Static Read Control to AUTO..

interesting indeed... worth a look later.. can't right now as E6750 G0 has an FSB wall around 490-495FSB

[ChaosMinionX]

Any ideas on 404 why it wont post with DRAM Static Read enabled? No voltage seems to do it, and the system just seems to throw up when I enable it.

[eva2000]

0404 already tightened latencies more than 0311/0403 personally i'd go with 0311 for more stability

As for me, if I set DRAM Static Read Control and Transaction booster BOTH to enabled, the motherboard will boot but NO post and screen.

I find there are only two options:

1. Dram Static Read Control set to Enable OR Auto
Transaction Booster set to AUTO

2. Dram Static Read Control set to Dissable
Transaction Booster set to Enable 0 or 1

Either options will boot and post fine, np.


Performance wise, I'm still uncertain which configuration is the best.
We all have seen EVA2000 excellent personal findings and contributions.
Now there is another new "Ultimate Overclocking Guide" done by X-Bit Lab with the new official BIOS 0404. The guys over there have some very interesting and informative results to disprove the "FSB Strap Change" in our mobo. Apparently, FSB Strap Change is solely upon to the user and not the mobo itself.

1.

The obtained results are given in the table below. The CPU in these tests worked at 3.2GHz. The memory frequency was set as close to 1066MHz as possible. The timings were locked at 4-4-4-12-8-30-8-8-8. Transaction Booster was set to Auto, and DRAM Static Read Control – to Enabled.

2.

In order to find out what the situation looks like on Asus P5K Deluxe mainboard, we tested the memory subsystem performance with the FSB frequency increment of 10MHz. the memory frequency in this session was set with the 4:5 FSB:Mem divider (this is the minimal divider available in the entire FSB frequency range). The CPU clock frequency multiplier was set to 8x. The memory timings were set manually at 5-5-5-15-11-42-10-10-10, so that the memory could work stably at maximum frequencies. Transaction Booster was set to Auto, DRAM Static Read Control – to Disabled.

3.

In conclusion to our extensive discussion I would like to say a few words to those Asus P5K Deluxe owners who for some reason believe that it changes FSB Strap at 500MHz. In reality there is no Strap changing whatsoever and cannot be. All tests that allegedly prove this statement haven’t been performed correctly. The thing is that if the DRAM Static Read Control parameter is set to Auto, the mainboard changes its value at this frequency. That is why the performance drops, which is erroneously considered to be caused by Strap changing. To eliminate this unpleasant effect, you should set DRAM Static Read Control to Enabled in the BIOS Setup.

*Question: Performance wise, should we set AUTO, Enable or Dissable for the DRAM Static Read Control. There's no doubt that with Transaction booster enabled 0 or 1, there is a significant performance increase. However, from my personal findings and with some of others, we'll have a problem upon booting with no post and screen when both DRAM Static Read Control set to Enable or Auto and Transaction Booster set to Enable 0 or 1. Only by dissabling the DRAM Static Read Control will remedy the problem.

[ChaosMinionX]

So Transaction booster (0) is faster than (1) right? And I have it set at 0 with DRAM Static Read to AUTO.....I had a problem with windows freezing, fixed by going to 30 on TRFC.

[Supershanks]

So Transaction booster (0) is faster than (1) right?

Not my findings. Boost level 0 =left 1=right

[ChaosMinionX]

My bad, booster 1 is faster than booster 0.

Just as I mentioned in Stilt's thread two weeks ago - post - if you can (which depends on how high FSB and Mem you're on) - the ideal set of settings as far as performance goes is: Static DRAM Control as Enabled, Command Rate at 1T, and Transaction Booster Enabled on Boost 1. But with increasing memory frequency, one will have to finally give up first on 1T, then Static Read Control will need to be Disabled, but even at DDR DDR2-1200 4-4-4 one should be able to stick to Transaction Booster Enabled at Boost 1. I have some screenshots at work, but forgot to transfer it to USB key, which show Dual SPi32M at DDR2-1212 4-4-4, with it Enabled on Boost 1. But at this speed, it was 2T and Static Control Disabled.

[Supershanks]

Dram Static Read control = Enabled
Note: cannot boot with Transaction booster =1



But that's quite a boost

[xgman]

Not my findings. Boost level 0 =left 1=right

I just ran the Everest test above and came out with 47.6 latency,
10,252 on the read and I haven't tweaked much of anything mentioned here (bios 0404). quad cpu speed is at 4.381ghz, but mem is at 486/584 5-5-4-15

here is a memset shot with nothing changed. Not sure what I should try tweaking different.

over 10K...WAY TO GO, Xgman!

[ChaosMinionX]

Performance level set to 7.

Great that's what I need to know

Performance wise(maximum bandwidth), which of the following will be your pick under the same clock speed (DDR2 1175 my example)?

1. 2T, DRAM Static Read Control Enabled, Transaction Booster AUTO

2. 2T, DRAM Static Read Control Dissabled, Transaction Booster +1

I don't know how much voltage you set for your rams at DDR2-1212-4-4-4 and with Transaction Boost set to 1. My mobo doesn't seems to like Dram Static Read Control and Transaction Booster both set to Enabled at the same time...even in as low as DDR2 800 and relaxed timings, 2T.....

[Supershanks]

2T, DRAM Static Read Control Enabled, Transaction Booster AUTO

is what i'd go for based on my tests. Only thing is as i found last night it works for benches but isn't orthos stable.

whereas

2. 2T, DRAM Static Read Control Dissabled, Transaction Booster +1

is at least 12hr stable

Thanks a lot! I think that could be why I'm getting random Orthos Blend fails anywhere from as soon as the first hour and up to ~7 hours 30mins.

I had a screen shot of ~10 hours Orthos small fft stable with 1.465v Vcore and FSB470*8 but I suspected it could be that my Vcore is still not enough all along so I'm back running orthos small fft again.

Right now I'm not even sure if it could also be my timings and subtimings are still a bit too tight at given Vdimm 2.2v (5-5-4-5/6/8/9-3-25-3-3-5/6/8)


Well, so performance wise as in max bandwidth, Dram Static Read Control Enable or Auto and TB Auto is > greater than Dram Static Read Control set to Dissable and TB +1 ? I'm just trying to find out what's the sweetspot for my configuration

[Supershanks]

I'm running 400@2:3 so 1200 5,5,5,12,3,30,3,3,3 vc=2.3v vc=1.525v

I'm just trying to find out what's the sweetspot for my configuration

that's why we're here
