Socket-A Sempry1600 OCing Q's

[fore1337]

Let's Abuse this little Sempron by OCing.

I picked up a $40 bundle for a “first PC” for a 12 year old for x-mas.

PC Chips M811LU(v3.1) mobo.
BIOS Phoenix
Sempron 1.6Ghz CPU
266 FutureMarks with an FX-5200 256mb, just crap! I'm trying to get him an R9600xt.
Memory: I will probably throw Corsair 512mb PC3200 Value in there, or something cheaper if I can justify it.

In the BIOS, my OC options are to tweak the FSB up to 165mhz

Stock: 133FSB x 12 => 1600, 32C

I’ve been running stable with these settings.
Stable @: 160 FSB x 12 => 1920, 40C

The bios maximum FSB setting is 165mhz.
I tried doing a wire Vcore mod trick to go from 1.60 to 1.80 Vcore… but the mod got me from 1.60V to 1.66V

Even if I successfully Vmod the chip to 1.8V the delta between 1920 and 1980mhz is negligible.

Is there any way I can change the multiplier from 12x to 13x or 14x ?
Given I do a successful Vcore mod from 1.6 to 1.8v and use proper cooling.

Cooling:
Stock HSK for AthlonXP 2400+ chip and 60mm Intel Fan (loud as hell)
I have a nice bootleg Zalaman Heatsink look-alike AL-CU HSK which will fit the socket 462.

CPU Database has an average OC for this chip @ around 2238 Mhz

I kinda missed out on the socket 462 or Socket-A thing. (went from Slot-A 750Mhz to Socket 478 P42.8C)

Mobo Random Specs:
KT266A/8235 chipset
BIOS AMI 2Mb Flash EEPROM, Supports Plug and Play 1.0A, APM 1.2, Multi Boot, DMI, Full support for ACPI revision 1.0

I wouldn't volt-mod a pc-chips board. Those things are just BARELY stable at their stock voltages. There's a reason you picked up that bundle for $40. The board is going to limit your potential greatly. It'd almost be worth your time to sell it and use that money toward a board with an nforce2 based chipset. You should be able to pick one on the extremely cheap by now.

It was my understanding the Semprons were locked down multiplier wise because AMD doesn't want you to buy them hoping for cheap OCs, which was killing their business before A64 was released.

If you want to overclock on socket A, get a real motherboard. Take the one from the combo deally and burn it.

Abit NF7-S 2.0 or AN7, even
DFI Lanparty Ultra II (or whatever the hell they called it)
Asus A7N-8X DX

go nuts.

Did you buy a Sempron 1.6GHz or a Duron 1.6GHz?

I think you have the Duron because 1) the $40 bundle was from Fry's, 2) Socket A Semprons use a 333MHz FSB and 3) Semprons are rated 2xxx+ and not by GHz.

I also picked up one of those bundles. The Durons are pretty weak compared (64KB L2) to the Semprons (256KB L2) and not just because of the cache but also the FSB. A better buy was the $99 Sempron 2200+ computer system. I have mine (Sempron 2200+ system) at 1.8GHz (from 1.5GHz) at stock voltage with a 400MHz FSB and PC3200 memory.

I was under the impression that it was a Sempron. it's got 64K of cache.

It is rated for 1600mhz and operates at a FSB of 133mhz x 2 ==> 266 mhz
I’m running it at a FSB of: 160mhz x 2 ==> 320 mhz (clock mult x12)

So no one knows if you can unlock the multiplier?

I can get my $40 back and pick up something else… I was just trying to not go overboard on price.

Looks like a decent NF2 board will be ~$50 & ~$70 for a decent CPU.
If I go another route, it looks like it will cost an extra $80 - $100. (dinero that could get him a better vid card.)

here's what it's got:

I think you have the Duron

yes, now that I'm home I could check it out.
