21x multiplier for X5650
21x multiplier for X5650
It would be great to have a 21x multiplier, but I can only choose between 20 or 22. This p6x58d-e isn’t working well—it caps at 208bclk—and I’m worried about instability if I go for 22. I don’t want to lower bclk too much for 22, since that could affect stability above 201bclk. My clock speed target is around 4.1ghz.
I came across some info about this earlier when exploring Gen 1 Core i for personal use. Generally, the X5650 can reach a maximum of x20, though certain boards might unlock higher numbers like x22 and x23 using Turbo modes and specific configurations. C3 and C6 seem possible, but I’m not sure about x21. I think x22 is likely available with multiple cores active and x23 if only a few are enabled. My memory might be off, so it’s been a while since I looked into this, and I’ve moved on to other options. You might be facing limitations based on your hardware setup.
I'm gathering more X58 boards soon, and I'll keep you updated on what works. My plan includes a G.1 Guerilla and a few UD3s. I can confidently say the Sabertooth X58 is amazing, while the EVGA Classified X58 is great but not very durable yet. With plenty of CPUs available, I need more boards to match them. Also, possibly higher wattage PSUs since my current setup is exceeding 800W when running at full capacity.
Looking into a multi-GPU configuration? Just running a 700W unit (actual 648W) with an X5650 at 4.2GHz and an RX 580 2048SP already showing limited gains. I'd cap it around 3400 MHz instead of pushing to 3600, which would require roughly 1.5-1.55V boost. That setup uses a 6x4 layout with some mediocre DDR3 RAM—clearly not ideal. You seem to be avoiding the hype from a while ago (like 1.35V VDIMM, 1.65V VDIMM, or 0.5V Δ). It looks like you're actually paying attention and running proper voltages now. With an 800W system, that's quite a power draw.
Ahahaha no I run crazy shit. My 965 pulls about 250W at 4.5GHz right now, and my GTX 580s (with heat killer blocks) at around 650W or so at the moment. More soon when I tune them further. This is a fun time project, which pretty much runs along with all my Core2 overclocking too. This is just an evolution. I can run over my settings this evening for you.
You're wondering about the configuration choices you're using. It seems like a classic retro setup with older GPUs, possibly from the early 2010s. You've fine-tuned the BIOS settings and adjusted the core voltage to balance stability and performance. The tweaks reflect a trade-off between power efficiency and thermal management.
It's a detailed recap of your evening setup. You're working on a retro build, specifically using a X58 Classy board. The shipping process damaged the socket, but you're trying to fix it. Right now you're running a clean Sabertooth, which performs exceptionally well. You enjoy pushing the BIOS clock higher and appreciate the performance boost, even if you have an EEPROM. You've previously pushed a 920 to 4.5GHz before getting your 965, and you know water makes a big difference—especially for voltage-sensitive chips. You're comfortable with high voltages and have plenty of RAM to handle the load. Over the past year, you've been expanding your collection steadily.
It seems like you're trying to figure out how to get the board to run at a higher frequency. You mentioned a few options, like using a cheap board, setting up a loop, or investing in a car project. You're also considering whether it's worth spending money on a water-based setup versus a more advanced cooling system. Keep experimenting and updating your plans!
Haha, I cranked my BCLK too high and messed up my 7 install. It felt like I went into the 200 range, even tried booting at 300. Activation files started disappearing from my setup, so I’m having to rebuild my M.2 slot. Likely the issue is using an M.2 drive with a PCIe adapter instead of a standard SATA SSD. My 975 struggles past mid-4.3s, but it boots at 4.5 and 4.6—still unstable. Voltage keeps rising into the 1.6V zone, and my water loop can’t keep up, hitting the high 80s. To speed things up, I swapped my XMS3 drives for a faster G.Skill TridentZ, but I’m missing one stick due to a mailbox thief. Right now I’m limited to 6GB, though it’s manageable and runs smoothly in the low 2000s.
