TAGG Posted July 25, 2018 Posted July 25, 2018 (edited) I just discovered a strange issue when raising FSB using SetFSB in Win XP, when I add more than 5MHz of FSB the multiplier starts to drop. This only seems to appear in XP, I used the same version of SetFSB in Win 7 x64 and it worked just fine (both CPU-Z 1.85)... Setup used was a ASUS P5E64-WS EVO and a Pentium E5800 but I also had the same issue on a EP45-UD3R but with 10MHz above boot-FSB... EDIT: Seems like a CPU-Z bug, CPU-Z 1.63 displays the right multi, but I can't use that to validate for obvious reasons EDIT2: The CPU itself isn't lowering clocks at all, spi runs are nearly the same within the 1MHz where the bug accurs... Anyone ever had a simmilar problem and might know a fix? Any help would be greatly appreciated Edited July 25, 2018 by TAGG 1 Quote
Noxinite Posted July 25, 2018 Posted July 25, 2018 Huh, nice testing. I noticed it on a Celeron 430 IIRC, but it was while I was binning so didn't test any benches. I found booting higher helped prevent it from occuring as soon; not a solution but the best I could find at the time. Quote
Members GeorgeStorm Posted July 25, 2018 Members Posted July 25, 2018 Interesting, not something I remember having issues with (using EP45-UD3P). Will keep an eye out next time I'm doing 775. Quote
TAGG Posted July 25, 2018 Author Posted July 25, 2018 Yep booting higher helps but only linear i.e. booting 400MHz instead of 395 lifts the bug to 405 instead of 400... I will try a brandnew XP install tomorrow... At least it's only a display bug, so benches are not affected, you just need to use antique CPU-Z to have the right Frequency displayed Quote

Does it show correctly? If yes then you can open rest of cpuz windows you need, then close the old version and take your screen shot. This is a trick that fixed weird issue with AFD on mocf for kabylake. No idea if it will work for you but worth a shot. Quote
TAGG Posted July 25, 2018 Author Posted July 25, 2018 Doesn't work, neither does the win98 version or anycombination of settings in the ini. file. As soon as you hit the threshold of 5MHz new CPU-Z displays one multi lower no matter if you have it open during changing FSB or if you open it afterwards if you had old CPU-Z open... Quote

TAGG Posted July 26, 2018 Author Posted July 26, 2018 Yes but which CPU-Z i use for taht doesn't matter, just for validation that's a problem Quote
Crew Strunkenbold Posted July 27, 2018 Crew Posted July 27, 2018 Could you report this bug to the CPU-Z authors? They usually ask for a report.txt. 1 Quote
unityofsaints Posted February 4, 2019 Posted February 4, 2019 I am seeing the same on the Rampage III Extreme with locked CPUs. Quote
ground Posted February 4, 2019 Posted February 4, 2019 9 hours ago, unityofsaints said: I am seeing the same on the Rampage III Extreme with locked CPUs. On 1366 you can get around it by upping the multi using Throttlestop. I've seen this issue on 775 (P5Q Deluxe and EP45-DS3) as well as on various 1366 boards (at least Rampage II Extreme, x58a-oc and x58a-UD7) and also on 1156 (H55m-UD2h and P55-USB3) Quote
TAGG Posted February 4, 2019 Author Posted February 4, 2019 You can bug it in the other direction as well if that helps as motivation to fix it, lowering bclk raises multi to impossible levels (see attached pic) 1 Quote
unityofsaints Posted February 5, 2019 Posted February 5, 2019 It's not unique to Intel either. On Ryzen on certain boards and multi combos CPU-Z will suddenly show 80 BCLK and wrong mult but right frequency. Very annoying when you are on LN2 and need a valid screenshot. Quote
Luumi Posted October 1, 2020 Posted October 1, 2020 It is only visual bug, even if CPUz drops multiplier the actual speed is with the max multi you had. Quote
Mrmouse Posted March 21, 2021 Posted March 21, 2021 Hi Guys A few Days ago i got the same Issue with an E5800 on an Asus P5E3 Deluxe/WIFI and Windows XP SP3. Like 'TAGG' said, even if you boot with higher FSB, the Problem is still there, it just moves. I tested all CPU-Z Versions down to v1.58. The Issue starts with CPU-Z v1.78. With CPU-Z v1.77 i got some fast "hopping" of Numbers when i start to rise FSB. But a few Seconds later it stabilizes. I have about 2 of 5 corrupted CPU-Z Validation Files with v1.77. With v1.69 no Issues are found. The Point is, like 'Luumi' said, that it's only a Visual Bug. But if i try to get some Validation File for high FSB or CPU-Freq. this Bug doesn't let you get the right Speeds. The Validation-File saves the "false-Multi", so if you Upload this File, you will have a droped Multi on you CPU-Z Validation Page. And using older CPU-Z is senseless, because you can't Upload these and on the other Hand you have to use 1.94+ for HWBot-Submissions: So... Has someone of you Guys found a Solution or a Workaround for this strange Behavoir? Thank you in Advance and best Greetings, mrmouse Quote
Crew Leeghoofd Posted March 21, 2021 Crew Posted March 21, 2021 as far as i know CPUZ site will not validate it, it will remain unchecked thus it is not valid here. We allow older cpuz to be used for screenshot purposes on the affected setups at HWBOT (see FAQ, last item) 1 Quote
Mrmouse Posted March 21, 2021 Posted March 21, 2021 Thanks a lot for the FAQ Haven't a look at the very Bottom. Just to be on the safe side; if i use old enough Hardware, there is no need to get a CPU-Z Validation on there Site (https://valid.x86.fr/)? So it would be enough, when i do a normal Screenshot instead of Validation-Link for CPU, Mem and FSB-Frequency? For me, the Validation-Page for CPU-Z doesn't take/upload any Files under v1.94; so i even can't upload them. You said "Unchecked" on the Validation-Website is not allowed for Submissions like CPU, Mem and FSB-Frequency? A lot of the Top-Overclockers have unchecked Submissions; you get them if you set CPU-Z to XOC=1. Was this a Time ago allowed or how is this Checked/Unchecked behavior in 2021? Best Greetings, mrmouse Quote
Crew Leeghoofd Posted March 21, 2021 Crew Posted March 21, 2021 Sorry no, CPUZ needs to get it sorted, we can't go with just a verification screenshot, it has to be a valid link at their site. Have you tried the Vintage edition of CPUZ? Quote
Mrmouse Posted March 21, 2021 Posted March 21, 2021 Yes, i tried the Vintage-CPUz-Edition, without success. Also i tried to move the CPU-Z.exe into different Folders with different .ini-Files. Tried a lot, but nothing seemed to get the Success. The only thing, to get rid of these Error on CPU-Z 1.78 to 1.95, is to set the Multiplier to 15,0x. Mulitplier 16,0 and 15,5 -> strange Behavior. Multiplier 15,0 and lower -> no Problems But this isn't for me a "real Solution"... Quote
Bones Posted March 21, 2021 Posted March 21, 2021 I'm thinking is an issue with newer versions of CPU-Z vs SetFSB itself, like it is with older Socket A systems locking up when you open CPU-Z with any CPU-Z version 1.60 and later. Although it doesn't happen with all Socket A's it occurs on alot of them, I've ran into that too many times myself. Also; Do bear in mind SetFSB is an older tweaking util and I seriously doubt it's been updated for a VERY long time now. If the guys working with CPU-Z can solve all that it would be great. Quote
dejan_bin_laden Posted April 2 Posted April 2 (edited) Hey guys same thing happened today, E5800 and Rampage Formula on SS, when using setfsb to go over post +10mhz it shows lower multiplier higher i get, how come this wasnt sorted in 2024 ? Any advice on this use case ? dejan EDIT: Question: Can I use an older CPUZ version on legacy hardware? Answer: Yes, HWBOT recognises that on LGA1156 and older hardware newer CPU versions can lead to wrong multiplier detection and even BSODs while just opening CPUZ. Therefore scores are allowed on these Legacy platforms with CPUZ version1.59 or CPUZ version 1.77 I found the answer in FAQ lol, will try tommorow thank you Edited April 2 by dejan_bin_laden possible answer Quote
