pat on 865 for lga775 is possible?
Thanks for the link cpulloverclock..
Thanks for the link :D
Will try it and post some feedback.
What is "DRAM Latency Parameter"??
thats nice but need more settings :D
good to see an intel plattform tweaker like codereds amd plattform tweakers :)
thx man :toast:
Works just fine, but very few options :(
good stuff, can't wait to see what the future versions will bring! :slobber:
Say to me what is necessary to put in ;)Quote:

that's about all I can think of. Does anyone know what the "Turbo" "Streetracer" and "F1" Settings in the Abit-BIOSes are doing? Guess they are tightening up some settings, I'm not sure which though.
Thanks a lot for this tool - I appreciate it. :)
It certainly does make the comparison between different timings a lot easier.
for the ram divider and Nb strap setting I dont know if it's possible without a reboot because with the AA8 he is necessary to rebootQuote:

111 is the most aggressive parametre (too)Quote:

Thanks for the link and the app. Options for enabling/disabling PAT and dividers will be really nice.
try to get access to all the ram timings you can :D
Great tool man , thank you a lot .
More controls would be divine :D
Excellent tool, it has made quite a few people happy :D Thank you
ctiaw seems to capture the new settings applied by the Tweaker
FYI : i875P Tweaker Findings
For my setup, Active to Precharge (tRAS) Max and Refresh Mode Select (RMS) values other
than the default seems to make system slower (that's just me).
You may want to determine the fastest settings (for these 2 parameters) at stock speed first.
The following pics are found from the i875P Datasheet that relates to the parameters in the Tweaker.

2. REFRESH MODE SELECT (RMS) (111 = Fast Refresh Mode)
http://www.PhotoCrib.net/is.php?i=6255&img=rms1.jpg
3. DRAM LATENCY PARAMETER (** not sure about these, best match I found **)
111 = Normal Operation, although reported to be fastest previously :confused:
http://www.PhotoCrib.net/is.php?i=6256&img=dramlat.jpg
Also, 3DMark2001 seems to be able to measure performance changes in CL timings better as reported by Hipro5 here

1. PERFORMANCE REQUIREMENT BIT (PRB MSR_PLATFORM_BRV bits [18])
This feature allows P4 Prescott (LGA775 & Socket478) to step down multiplier to the lowest in its class (x14 for Prescott). Tom's Hardware article
I have found a document that indicates this feature (PRB) applies to Xeons as well.

2. CPU MULTIPLIER ADJUSTMENT FOR XEONS (IA-32_FLEX_BRVID_SEL MSR bits [15:8])
By default, highest operating multiplier is set and used for the CPU. It can be adjusted as described by the document below, but I am unable to find the address of the MSR, BIOS programmers will have this info. I believe the tweak can be applied to both Nocona (FSB 800MHz) & Prestonia (FSB 533MHz) Xeons.

New version here : http://www.cpuid.org/download/Tw865.zip
- some bugs corrected
- a performance mode parameter available
- U can save with the Tw865.exe -file=save.txt command
Great app there cpulloverclock/franck :toast:
I tested changing Abit's Game Accelerator settings on my IS7 to see if any of the settings in your app changed: -
'Game Accelerator' -> Changes 'Performance Mode' (as expected) (Auto = Disabled, Turbo+SR+F1 = Enabled)
'Refresh Cycle Time' -> Changes Nothing
'Read Delay (tRD)' -> Changes Nothing
'Read Delay Adjust (tRDA)' -> Changes 'DRAM Latency Parameter' (Disabled = 00, Enabled = 10)
'CPC' -> Changes Nothing
So, if tRD and CPC (and whatever 'Refresh Cycle Time' changes) options could be added in a future release that would be well appreciated.
can someone please explaine to me what this programe does ? :stick:
It allows you to bypass the BIOS settings and change the memory latencies in Windows. Furthermore it lets you choose some options that usually are not even available in the BIOS. :toast:
Does it work under older Windows versions now ? I use WInXP and Win98Se dual boot.
what is the "other" option does ?e
where can i found a explnation that in understandable for what do each option and how is effacts the system ??
In the new version the PAT On/Off option works only with the 1:1 ratio. If I use any other divider the BIOS turns PAT off automatically and trying to reactivate it in Windows with the tweaker produces no effect.
So is there a way to have PAT ON while using a memory divider on a 865 mobo? Or is it just physically impossible?
http://www.xtremesystems.org/forums/...ad.php?t=44853
thougt maybe this will be interesting for you :)
move this thread to the intel section and stickied it :)
I would also like a bit of guidance :)
I am quite new to the extreme modding and clocking scene :)
you mean a guide on how to use this tool?
So theres no way it will work on 98se? I would like to see if i could get more off me chip on air.
great this tweaker
so what are best settings for 2x512...
i have this BH-5 that did 2-2-2-5 cpc off 2.5v DDR 400/2.8v CPC on with my dfi infinity and now i cant get it 2-3-2-5 stable with 2.8 volts on this IC7-G...
:confused:
Your BH-5 more than likely needs more volts (~2.95v ~ up to 3.6 :D )Quote:

but im only running DDR400, they ran 2-2-2-5 on my nforce 2 with 2.5v, and they cant run 2-3-2-5 on my IC7-G with 2.8v...
?
i have to have some settings wrong or something...
whats the best IC7-G bios, im just using the one that came with the board.
also, what the best place to buy some pots for the mods im planning out hehe?
Nice tool.
How does it load settings @ windows startup ?
Is there any way i could get this thing to load on 98 im looking to see what kinda bandwidth i get with my 2.0a but it is stuck with a 3/4 divider with no way to change it and a 3/4 divider realy sucks at 3.0GHz and evan more at 3.6GHz
any way to get this tool to work on asus p5p800
if i set PAT enable it dont run faster
Awesome app.
thanks cpull
Great tool, but I would love a save point!!!
The performance mode "enabled" gives another 100MB/s in Sandra though it won't be detected as "enabled" bt CPU-Z, but better this utillity fixed the bug I had with my Mushkin PC3500 LVL2 (BH5). They currently run 3,3v and 250MHz CAS2-2-2-5 without memtest errors, but in Windows they will render visualartifacts when playing games. Changing the DRAM Latency parametre to "01" fixed this... I just have to do this everytime I booted the computer.
Any way to modify it for a permanent "01" setting? I'm having a Asus P5P800 (LGA775 hybrid board with 865PE)
it would be really great if it could load the settings at startup.
mmm i get a re-boot when i use this tool :mad:
what is PAT ?
A technology wich lowers the latency between the memory and northbridge. Officially PAT (Performance Accelerated Technology) is only supported by Intel's high-end chipsets such as 875P, 925X and 925XE, but various motherboard manufacteros have managed to enable the feature on mainstream chipsets such as 865 and 915 series, but most of them don't work above 200MHz FSB.
ah ok, does it give much better performance ?Quote:

Is it possible that it could limit the board or CPU at FSB220, because there is no way I can get my 3.2GHz NW and a P4C800-E Deluxe further. And if so, how do I disable PAT?
Would it be able to implement an FSB adjustment? Great tool ;)
3.52 ghz isnt that bad, maybe its a cpu limit, but maybe try running in 5:4, if you can break 220 then you pat might be limiting you...or perhaps just your ram is limiting you.Quote:

How come you guys can set 111, 101 etc.?
Cheers,

In some earlier version it used to be 3 digits, now it's just two.
guys i founded really fast for pi 2-2-2-5-70us-64us-00 the pat, disable of course over 200....
Malachia - I too adjusted my Refresh settings from 70 to 120 and from 7.8 to 64us. However, I experienced some very wierd OS errors, crashes, and screwed up User Profiles in my XP SP2 installation. I'm still diagnosing the cause, and these particular tweaks may not be to blame, but I thought you would want to know that these settings might carry some small risk. I really loved using 'em too, cuz they bumped my Memory performance quite a bit. In Everest, my Read went from 6300MB or so to almost 6600MB, CTIAW saw a boost of a/b 200MB, and SANDRA 2005 also saw around 200MB to both Read and Write. They also added to my PCMARK 04 score. I wish that there was more activity in this thread, and with this App, because I really would like to have the benefit of others experiences to a similar degree as with the A64 Tweaker.
damon69
with the settings above i have get the best performances without limiting oc, there are better settings that you can gain 0,2s but they limited my oc too much!!!
I agree, my OC has been highest with these settings. I read an article which discussed the nature of the refresh rate and the fact that our favorite settings would tend to relax the stress on the RAM, thus enabling higher FSB. In fact, all of the other Tweaks available with this Utility are apparently too much for my XMS3500C2 (BH-5), cuz I get an immediate BSOD or Freeze Up. I just wanted to point out that I have experienced some OS corruption issues since employing the tweaks, and give you a heads up. Be well, brother!
damon69
I can't make it work on my Asus P5GD1 PRO. Only the i855 works. The 865 gives an error on load.
I have two machines in here, and also would like to have much more choices on the P4 as I have on 3000+ with the A64_Tweaker.
Anyone ? :D

guys is true that with PAT enabled you have not more agp/pci fixes??
has anyone tried this software on dfi 875-t ?
It's true that PAT doesn't work at high FSBs on 865PE chipsets, which are basically binned 875Ps as I understand it. I always run my RAM 1:1, and currently I've gotten my 3.0E stable at 253fsb (3.8G) but with PAT enabled I can't even boot at 233fsb (3.5G) and it usually does that on air and stock voltages. Anybody want to trade an IC7-G for an IS7 with heatsinks epoxied all over it? :rolleyes:
edit: Oh yeah, and there is nothing wrong with my PCI/AGP lock with PAT enabled. The chipset just can't handle the tight timings at high FSB.
-Luf
great tool!! helps allot with dell 400sc. Can take advantage of my hyper x tighter timings. Thanks
Could some one please walk me through how to force the 'DRAM latency parameter' to 101, using wpcredit and pmem or wpcreset so that the change is _permanent_. I have some compatibility issues with OCZ ram on my P4P800 D, and this solves it.
Can we use parameter to tell Performance Mode enabled when booting up (adding short cut to Startup folder)? How?
Links seem to be dead..... Just got my P5P800 setup and was looking for a tweaker....
Just tried this little app in my Win2k installation. Adjusting to 11 just causes the computer to reboot, either that or lockup, even at stock, SPD timings and with PAT off. Something is mucked up with this program.
Hey, this link is busted. Can someone possibly email/aim/msn it to me? Please? I wanna get PAT :D.

Now my question is, is there any way to hack the registry or bios to keep that 01 setting always without having to change the timing each and every single reboot.
Oh yeah I forgot my basic system specs
ASUS P4P800SE, INTEL 3.0C
KINGSTON PC3200UL HYPERX
WD 10,000RPM 74Gb raptor
Nvidia 6800GT, Audigy2
OCZ 520watt Powerstream PSU
My preference would be a modded bios to flash into my system but I don't know how to mod a bois especially to figure out how to find and change that one setting. The next best option I could think of would be a registry hack. What I am doing now is I have that I865/I875 tweaker program in my startup folder so every single time I reboot it starts and I have to change the timing manually before I play games or else I get graphical glitches.
You migth be abel to make it an outo start up file.
Or maybe you could tell us what mobo You have.
The AI7 I use with BH-5, has good timings already, I got it at 2226 F1 S 3 D D
The tweaker, the only thing that made 0.5% improvement was changing RMS from 7.8us to 64us
I totally don't understand that, shouldn't 64us be slower than 7.8us?
Nothing else gave me any improvement at all. changing CAS 2 to other (11) gave me a huge boost, but the ctiaw locked up right afterwards.
Of course 64us is better, the longer the DRAM refresh interval is, the more (time) the memory is available for transactions. Isn't it better to have a refresh cycle at 64us than 7.8us ?
Place the program in the startup folder, loads automatically, but...
I need to know how to make it set the DRAM Latency Parameter to 01 automatically, then exit.
So I don't have to do this manually everytime I reboot. This 01 setting fixes graphical glitchs on the i865 chipset.
Help please, I will be very thankful.
I have been using a Hex Editor on the program, I was able to change the 00 to 01, but it had no effect. Seem that I can only edit the text within the program.
The SAVE button function does not work, it only outputs a txt file. I don't understand this.
Does it work with the pentium-m + CT-479?
Cannot see why not. The tweaker is for the chipset/mem only, not the cpu.Quote:

ok, think I have it figured out now, place in startup folder with "C:\Program Files\Tw865\Tw865.exe" -file=tw865.txt
appears to be working. No more 865 glitchs
yes it does work with it. I had to use it since the bios sets the timings to 2.5-3-3-6 for my ram even when i have manually set it to 3-4-4-8. I cant disable pat unless i use this proggy.Quote:

actually it is 200 and up with pat partially on. just check it with ctiaw... anyway
01 should be best regarding lax timings. might even set tras max to 120µs did
get me above 306 mhz fsb :)
00 and 01 are. 11 is really CPU speed killing!Quote:
