FSB O/C'ing Bottleneck?

[Egon]

Question/Issue...

I have an Abit KT7-Raid, Duron 600 o/c'd to 880 (8x110) with 128 mb generic PC133 and Creative Graphics Blaster RIVA TNT (PCI). The issue I have is that I can't o/c the FSB beyond 110...any thoughts as to whether this is more likely the RAM or Video Card? I can pick-up 128MB of Micron RAM @ $69 Cdn but a new video card will run me at least $150.00+, so I'd appreciate any thoughts.

Thanks.

You've about reached the limit of the FSB. You need to adjust the CPU multiplier up 🙂

Most Duron FSB can not go high. Up the multiplier to get more mhz

Egon: I have a Duron 700 overclocked to 1083 on an KT7 nonRAID mobo (10.5x103). My FSB peaks out at 103. Before you start buying a new video card or RAM, lower your FSB and increase your multiplier. You will get a greater MHz increase and your system will be more stable.

Yeah, its the VIA chipset. I max my kt7-raid at 112 FSB, at any multiplier on my duron. generally speaking, this board will max at 110 or so; a FSB of 103 max is just very bad luck, at 112 good luck....

I just hit the ceiling on my TB750@1071 I can only get 102FSB w/10.5 multi selected. Every bump after 850 I lost one FSB setting,slowly getting lower and lower. I Am going to run it here for a while and maybe back down the multi for a higher FSB 9.5x105 or something...?

yeh I heard most don't pass 110, or roundabout's. For some reason mine runs up to 117 MHz FSB (but not 120) it's pretty encouraging. I'm just starting my overclocking. I guess it depends on each individual board. btw I have Mushkin HSDRAM

I have some mosel vitalic that will do 114 stable my old cheap ram would only do 103 in my system.
