I.nfraR.ed

The bad thing about this tools is that it's x64 only. The only app that works on 32bit Windows I know of is ZenStates, but it has limited functionality and requires vcore in "AMD Overclocking" mode, not fixed. That's if you want to change VID. You can always set frequency.

New version of the tweaker. Started from scratch and ported all the functionality from the previous app. This is a native one and doesn't need .NET framework, which results in much faster start up. There are several improvements and new settings, FSB slider doesn't do anything yet. Source: https://github.com/irusanov/nForce2-xtreme-tweaker-vcl NForce2Xtreme-v1.1-beta3.zip

I have encountered the same thing while developing the nf2 tweaker. When booted with 1:1 you can then "set" any FSB:DRAM ratio and cpuz is easily fooled, because it seems to read that register. https://valid.x86.fr/zukryk I've obviously exaggerated "a bit" with the 3508MHz (DDR-7016). 1:15 is the highest possible. CBID tool is reading DRAM frequency correctly, so I'm trying to find how to reproduce it and report to Franck. Makes me question the validity of the current top-1 valid for socket A (except that one of from @digitalbath). Not calling anyone cheater, but it might be another honest mistake. The thing is we were all stuck at 300.7 max, while the Greeks managed higher. Not saying it's impossible though.

Is that supposed to be a hidden thread? I don't see the competition listed yet and it seems some people see the stage limitations...

True. I was expecting minor revision to be higher for newer CPUs, but it seems there's no such correlation. There's also no correlation between the minor revision, the PCB revision and the gold letter in the corner. Common versions for Barton are 2, 11, 12, 15 and as @Tzkpreviously wrote, 12 and 15 are reported as unlocked, while 2 and 11 are reported as locked. This doesn't 100% correspond to reality, since it depends on the production week, too. One of my 2s are unlocked and one 12 is locked. Overall the detection success rate seems to be high. I will re-check those 2 CPUs to make sure it's not an error on my side. Thoroughbred B has revisions 2, 6, 13, 14. 2 and 6 are reported as "Unknown", 13 is reported as "Undetermined" and 14 as "Unlocked". In reality, 13 seems to be the only one that is locked. 2 and 6 seem to be from 2002, others are 2003 and 2004. There's one 14 from 2002. I have one Applebred B0 (Thoroughbred-B) which is 14 and is locked, produced in week 0347. All Thoroughbred-B Semprons I have are 13 and are locked. Also later production weeks, which "guarantees" a super locked CPU. 11 is B in HEX, 12 is C, 13 is D, 14 is E, 15 is F. I guess the highest possible is 15 (F). According to the documentation, it's bits 3-0 (4 bits), so 1111 = F is the highest. Edit: For Applebred/Thoroughbred the following seems to be valid (with one exception again, which I have to recheck) xxxHB (e.g. JIUHB) is 14 xxxCB (e.g. JIUCB) is 6 xxxJB (e.g. KIXJB) is 13 xxxXB (e.g. MCXB) is 13 xxxGB (e.g. AIUGB) is 2 I'm sure BCRC is guessing the "Crystal Marker" based on the minor revision and codename. The theory is that this minor revision is something like a range of letters. Same applies to the major revision, which is indicated from the last letter, e.g. JIUHB, where B = 1 for "Thoroughbred-B". In case of a Barton, we have A = 0 there, e.g. IQYHA. I'm kind of sure about last letter now. The minor revision is probably "encoding" for more than one letter. This timeline with steppings might help us reconstruct the lookup table: https://www.cpu-world.com/info/AMD/amd_stepping_K7.html https://www.cpu-world.com/info/AMD/K7_stepping_codes.html

I bought it mostly for the board, the CPUs are not interesting. The board capabilities are unknown until properly tested. Free up

I've been going through some of my CPUs. I forgot to note the reported core by BCRC for some of the first entries in the table, so take them with a grain of salt. The lookup table for those cores is not 100% correct anyway.

Note that the CPU in red is FAKE Thoroughbred-B, in reality it's T-Bred A instead with L3, L5 and L12 bridges manipulated and has fake markings. Up to the "Unlocked" column are values either written on the cpu or detected from other tools. Unlocked column is based on testing. Rest of the columns are from BCRC and the tweaker. I will also check what Palomino reports, but that MSR is invalid on Thunderbird core, so maybe it's the same on Palominos. PS: Maybe we should use some shared google sheet, since you can't really format the tables here.

My boards are going down one by one without doing anything special, so I had to take the chance.

Yes, this seems to be common with ATI, not sure what the reason is. Even with a 3GHz CPU and VGA@999/1140 I could not get above 300 on CL and only hit about 110 in CH.

These "possible crystal marker" and "possible parent crystal" are just educated guesses based on other parameters. The multiplier type is also probably guessed based on some parameters (major.minor rev, but maybe something else too). That minor revision is kind of strange, I would have guessed higher minor revision would mean a newer cpu, but based on your table - that is not the case. I've added a message box to the tweaker on app open that displays the info I currently have implemented. There's not much info about the topic, but K8 KBDG (BIOS and Kernel Developer's Guide for AMD AthlonTM 64 and AMD OpteronTM Processors) has the MSR register in question documented There's one more value, which is "Reticle Site" and I've included it in the info. Curious to see what different cpus show. Btw, reading and writing MSRs is quite easy. You can use the MSR Editor and MSR Walker in CrystalCPUID tool. PS: I'm thinking of writing a small tool that automatically dumps CPUID registers, MSRs and all the info like cpuid, name, family, model, revision, etc. This way, the comparisons would be easier and faster. Edit: Replaced the app with new build. I was reading wrong part of the register, but it should be ok now. nForce2XT_Debug_20210703.zip

Awesome!

Yes, this has so much potential. I was fighting with the board for several hours and managed to complete just 2 runs :D Had a better one with better timings, but with a bugged troll's lair.

Yes, I've seen the same, but better structured changelogs, here: https://www.lejabeach.com/DFI/BIOS/dfiultrabbios.html I've compared them in the past, but not so extensively. There's a mention about "improved" 3D Mark 2001SE performance, but I don't know if the changes are in the romsip tables or somewhere else. Maybe it's worth checking performance of the bioses "as-is" on a real Ultra B first, with same manual settings on diffrerent benchmarks, but that's a lot of work. 2004/01/31 2. Increase 3DMark2001 SE performance (compare to 12/31) AFAIK that 15 10 doesn't work and it had been changed in most (all?) modbioses. Apparently Oskar Wu changed it too. I believe what you've shown on the right side should be close to optimal for all boards with all multipliers (the multiplier tables part). NF3 and NF4 bioses also use "E4", although I don't know how relevant it is.

Yes, even stock 7800GS+ scored 100fps at CL and CPU @ 2500. 107+ fps with CPU @ 2750. You can try 7.11 and 8.4/8.5 drivers with the 1950X. Nothing would come close to 3850's Nature performance though. I guess you use specific test order and setlod?

Yes, tried different bioses and different values in the tweaker. I may install your modbios with the predefined romsip tables to check, but so far nothing helps.I can boot 260, but no stability, 255 is on the edge and usually experience a sudden force close while running a test (mostly on the "high" ones). 253 was ok. AGP bus up to 105MHz and voltage up to 1.8V didn't make a difference. Kind of want to try a KT880 board to see if it will be the same. I have a Delta-FSR somewhere in the closet.
