Agp/pci frequency lock at 33 mhz ??

how can i lock the agp/pci frequency at 33 mhz when i overclock p4 1.8a to 2.4 at fsb=133 and vcore at 1.425.... because windows xp can't start up . it keeps rebooting the pc ,,, please help
i have msi 645 ultra ddr333 ms-6547 mobo

That board and chip really only supports 100fsb :D
anything over and its overclocked!!!!! ;(
there is no stuff in tha bios to lock agp or pci ;(
Most people think overclocking is ok ?( Just buy faster next Time 8o 8o

Agp/pci clock locking help please

i have the 865pe neo, using patriot memory with winbond 5ns chip, have no problem running at 250mhz in corecenter, however when i try to o/c in bios, when with the agp/pci clock locked, i can still it increasing up to 80mhz/xxxmhz as i increase the front bus speed of the cpu, anyone having the same problem with this board? will new bios fix this? by the way , i can't manually change the agp/pci clock , it's grayed out and "locked" this ths only option available under "apg/pci clock" there's no manual setting, soeone please help i can bring this board back to get the 875p if thats needed
thanks fo ryou help

Hi tgn,
MSI have this feature locked to prevent us from o/c the CPU multipiler settings. Can't say that whether this is good or bad for o/clockers like us. Unlike Abit which unlocks everything, MSI keep settings to what the mobo detects the CPU model is, i.e, if you're running a P4 2.4, then your Multipiler settings will be 18x with 133 FSB x 4 to make 2400+- MHz, try calculating the mathematics way and you'll know how far you can o/c to.
Corecenter o/cing is another way MSI sets as it will directly show you the speed your CPU is running at vs the multipiler settings.
All the Best... :D!!!

PCIE frequency locked on K9N2G Neo?

Board: K9N2G Neo (MCP78-S/nvidia 8200 chipset)
Bios: AMI v1.1
CPU: AMD X2 6000+
Hi!
I am just about to try a bit of overclocking. There is no option in my bios regarding locking PCIE frequency.
It could be locked automatically, I just want to make sure.
I tried several programs to read out the PCIE bus speed, like Everest, Sandra but they did not show it.

Yes, it should be locked by default.

PT880 and AGP/PCI Lock---is this it??

Have visited Viarenea and others----supposedly Via has instituted an AGP/PCI Lock for the first time on their chipsets and the PT880 board is the first to have it.
I found this in the Manual----Frequency/Voltage controls in Bios:
Page 3-28
AGP Frequency
This item is used to configure the AGP frequency. Settings: From 66.9 to
100.9 at 1 increment.
Am not sure----but I believe this setting to be the long absent AGP/PCI lock setting that Via was notorious for NOT having----but supposedly fixed with this chipset.
This sounds very similar to Bios settings on various NForce2 boards that DOES lock the AGP/PCI bus
Anybody know anything about this?
Basically, an AGP/PCI lock is ESSENTIAL for any kind of serious overclocks.
Thanks----John

You are Absolutely Correct "johnrr6", This is VIA's new AGP/PCI Bus Lock/Divider .....And it is About Time!!!..........Sean REILLY875

K8T Neo AGP/PCI lock - never here?

Anandtech states on their review:
"We contacted MSI, who told us this will be included in an upcoming BIOS upgrade."
Have we ever seen this AGP/PCI clock lock?

Via themselves reported that in the K8T chipset they could not get it to work. That is why they built the K8T pro chipset. The Neo systems with the original K8T chipsets can not nor ever will have PCI/AGP lock.

How do I unlock the AGP/PCI for MSI 865P Neo?

I tried to overclock my P4 2.8GHz by changing the FSB. I noticed that the frequency for AGP/PCI and memory will change together with the FSB. I am unable to just change the FSB only. How do I unlock the AGP/PCI frequency so that only the FSB is changed? If not, i can't do overclocking.

Hi msklee,
I dun think that we can unlock that in the features as it is BIOS controlled... If you find that after you o/c and things are too tight and system will not boot up, juz lower your o/c specs and it should do well.
By the way, I hope that you do not spam the forums with the same thread repeatingly juz to ask something similiar , so I will close the rest of the similiar post to ensure pple dun answer here and there, and you dun have to go so many threads to get solns too... In the future 1 thread will do all .
All the Best... :D!!!

MSI Pro2-C (6562) - How to lock AGP/PCI clock ?

hi,
I use the BIOS 1.1 with this card, and can't lock the AGP/PCI Clock (66/33)
Is there an utility which can do that, or is it possible with the BIOS 1.2 ?
thx

-> LINK to the MB specifications.
MSI Pro2-C / MS-6562_i845
With this bios (1.1), I can't lock the agp/pci clock to 66.66/33.33 and when the FSB is about 105, pci extensions are out.
So, I would like to know if it's possible to lock agp/pci clock with the BIOS 1.2 (or maybe another bios), or if it's possible to do that with software (and if yes, which software)
CPU is p4 willamette 1.7 (17*100) and I think it would be possible to reach a fsb around 120 (@2040 Mhz) if I can lock agp/pci clock.
thanks for your help
and sorry for my english, i'm french

Lock agp/pci clock with software

hi,
I have a MSI pro2-C (MS-6562 100 rev0.4) and can't lock the agp/pci clock with bios.
Do you know a software which do that ?

PT880----is the AGP/PCI lock working???

I ran across some interesting results looking in Aida32 at my V-link thruput under motherboard.
It was showing a 77 mghtz clock----and my thruput bandwidth was way higher than the mode 4 setting max of 1066. Makes sense----why not---but shouldn't it be locked to 66.6 too??
It appears that overclocking also overclocks the V-Link clock and bandwidth.
Now I know that technically V-Link is NB-SB connections speeds-----and may not have anything to do with the PCI/AGP bus.
But I have had some folks tell me that NB-SB connections are directly entwined with the PCI/AGP bus.
And-----VIA is claiming that the SB hosts the RAID controller now----and it doesn't use the AGP/PCI bus in the classic way.
So----I guess what we need to see is evidence that the PCI/AGP bus is actually running at 66.6----even when overclocked.
Anybody know software that will tell us that----In Aida somewhere??
Thoughts anyone?? Am I mixing apples with oranges??

If anyone got this PDF ?
johnrr6 => The value are you reading is the frequency of communication bus between NB & SB(not the PCI freq.), on my Intel board is the same when i push the FSB highter. And it's normal and the PCI Bus still locked .
The good test for PCI Fix Working for me, is my sat tuner card and my SCSI card because when i increased frequency of PCI bus => theses cards become crazy (CRC errors, SCSI Bus reset randomly on my SCSI card & many lockup, heavy graphical corruption on my sat tuner card) if the frequency of PCI Bus isn't near of 33Mhz.
Thanks----excellent explanation----so I was basically comparing apples to oranges------differnt buses entirely.
Same clock chip for me: ICS 952911BF-----there were some other numbers on it----do you need those??
Different subject---but along the same lines------am starting to see a cold boot problem at anything above 225 FSB
Computer will initially boot fine----run stable----no problems----then when I go to Start>>>>>>shutdown----and do a normal shutdown.....it shuts down fine....
But after a normal shutdown, it will not reboot for several tries----then----all of a sudden it will reboot fine on one of the tries.
If I pull the power cord and let it sit for a minute-----it will usually fix the problem and boot fine.
Any suggestions???

Locked AGP/PCI

Can the k7n2 delta-ISLR lock the AGP/PCI bus?
Want to OC a 2600XP with corsair PC3200LL.

the AGP clock frequency is set at default (66).
Should the PCI auto detect also be enabled?
Is that all that is needed to lock the AGP/PCI bus?

So does the AGP/PCI lock work or not??

I have read many contridicting reports as to whether the AGP/PCI lock actually works on the K8N Neo Platinum.
Some say yes, some say no, some say setting it to 67 in the bios enables the locks. Does anybody actually know for sure, and not rely on that Clockgen thingy?? Also, if it must be set to 67 for sure, will this be addressed in a future bios release??
I am currently a bit scared to begin overclocking when I hear about RAID sets dropping out on the account of unlocked buses on a board that is supposed to have locked buses.....

I heard if you changed the AGP bus to 68 it will still lock but you will get much better overclocking results...

KT266 PRO2 RU, can it lock AGP/PCI??

There is some way to lock the AGP/PCI bus in this mobo?
Greetings.

nope it just uses dividers like all via boards

Does MSI K8N NEO 4 have (agp)/PCI lock?

hi. yeah, Does MSI K8N NEO 4 have (agp)/PCI lock? I saw only the PCI-E lock (100MHz)

Quote from: gpalmer on 03-November-05, 21:18:07
the neo4 does not have AGP.
No, I know it. "( )"
Quote from: Richard on 03-November-05, 21:29:27
Paradis,
The PCI, IDE and SATA are locked.
Take Care,

okej, thank you. I feel me safe now :D

Does My MS-6534 Has AGP/PCI Lock Feature?

Hello, I would like to ask, does my MSI MS-6534 i845 has AGP/PCI Lock feature?
http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_detail.php?UID=40
Does it support overclocking?
Cause I want to overclock my CPU and I afraid it will cause some damages to my VGA Card or PCI slot card.
My PC specs:
Intel PIV 1.5 GHz (100x15)
SDRAM 256MB + 128MB PC133, total 384MB
Seagate 7200.7 40GB
Sapphire R9500 128MB mod to R9700
PSU 400 Watt
Last week my soundcard didn't sound anything after I set my FSB from default 100 to 113.
And then my PC boots so slow.
I play Wining Eleven 7 adn it goes slow, not as usuall.
Does somebody can give me some solution.
Sorry for my English.

I afraid that my VGA card was damaged cause i overclocked my CPU too high.
Are there any indications of damaged VGA Card or other peripheral like harddisk or soundcard?
I so afraid.

Do k8t neo fis2r have agp/pci lock?

Hi
I just read a test of my motherboard (MSI k8t neo fis2r).
I was written that the motherboard had a agp/pci lock.
Does it so? I dont want to damage my 9800xt with to high agp bus so i need to know! please

Simple fix... Don't overclock the system clock or what people mistakenly reffer to as the Front Side Bus (FSB)... The issue is not just with the motherboard but rather with the VIA K8T-800 chipset. The Hyperthreading, PCIO, and AGP are all tied to the system clock so when you change that clock everything is affected. Some things can handle it and some things can't. If you leave the system clock alone then there are no worries.
