Alienware Overclocking Guide
It’s clear I’m still confused. Purchasing this unit for 2k in a bind on Craigslist was only the start of my confusion, even though it came with 32 gigabytes of DDR4 G.SKILL, 2 980 MHz and a 2T 850 Evo looks like a good deal. The frustration is that Dell won’t let me upgrade it. Their software allows adjustments for individual memory slots—such as changing CPU BCLK Speed, ring ratio, cache/turbo ratio limits, and core voltage—but never the non-turbo CPU ratio or memory speeds (except in UEFI), nor the voltages. The utility would let you tweak each slot’s settings if you set the DRAM TIME MODE in BIOS from auto to link, where you could also adjust the DRAM frequency.
These BIOS options are perplexing:
CPU Ratio Mode [Dynamic|Fixed]
Does this...-:
A.) Turn off turbo mode? That seems odd since turbo mode isn’t a disable option... but if it were set to 45... would that require increasing the CPU Power Management settings?
Options like...Long Duration Power Limit (in watts [since I can’t guess the base ratios, what formula should I use to calculate wattage if BCLK is 125 and turbo ratio is 40, what should the long duration limit be?]);Long duration maintained;Short duration power limit)
B.) Perhaps it relates to those C5/C6 Has with C-States...
And then there are the Overvoltage Configurations in the BIOS:
::MEMORY VOLTAGE (24h OUT1)[0-80]
::MEMORY VOLTAGE (26h OUT1)[0-80]
:
😀
My mind is stuck—I’m left wondering if I should just set BCLK to 105.9, which is the maximum it can handle without crashing, and configure memory to 2400MHz, then attempt to overclock the 980s until I get a new machine... unless someone suggests an alternative. Please let me know if there’s anything else I could do to clarify.
Sorry, I did this on my phone because fixing my computer isn’t possible right now...>_<

Hmm..... those mutha fuckas
Well, sorry about that. If you can, try changing the motherboard to an aftermarket option such as Asus, ASRock, Gigabyte or MSI and use the unlocked UEFI BIOS from any of these brands. This should give you much better performance because they all support multiplier OC and BUS OC.

Hello,

Now there is a lot I don't understand. And clearly getting this box for 2k in a bind off craigslist was just the beginning of my mistakes even if it did come with 32gigs of ddr4 g.skill and 2 980s and a 2T 850 Evo seems like a steal. The frustration is Dell won't let me break it. Their soft wear let's me modify CPU BCLK Speed and what appears to be the Ring Ratio, cache/turbo ratio limit and core voltage. But never the Non turbo CPU RATIO or memory speeds(except in Uefi), or voltages. The software would let you change for each individual memory slot what you could change if you set the DRAM TIME MODE in the bios from auto to link, where you could also change the dram frquency.
This are confusing options in the bios like:
CPU Ratio Mode [Dynamic|Fixed]
Does this...-:
A.)Disable turbo mode? That doesn't make since turbo mode as a disable option...but if somehow set to 45... does that mean that the CPU Power management Configuration would all have to increase?
Settings like...Long Duration Power Limit (In Watts [Since I obviously can't chance the base ratios what formula can I use to determine wattage used if BCLK was 125 and turbo ratio was 40, what should the long duration power limit be?]);Long duration mantained;Short duration power limit
B.)Maybe it was those C5/C6 Has well C-States they were talking about...
And then there are the Overvoltage Configurations in the BIOS:
::MEMORY VOLTAGE (24h OUT1)[0-80]
::MEMORY VOLTAGE (26h OUT1)[0-80]
:
😀
MI and Uncore VOLTAGE (2Ah OUT1)[0-55]
::CPU VCCIN [1.8 V-2.5 V]
Besides THE CPU input Voltage I'm at a complete lost... I can't find anything
So basically I'm just thinking I'll probably just set the BCLK to 105.9 which is all it can stay at without crashing and set the memory to 2400Mhz and try and Overclock the 980s I have until I get a new rig... unless there are some solutions someone could offer... please tell me if there is anything else I could provide to clerify.
It seems that Dell has locked the BIOS down to where you can only do a front side BUS OC. That means that when you OC that, you OC the northbridge and its communication to your RAM and CPU, but not the CPU directly. So, your OC is unstable because you OC is actually overclocking your CPU, mobo (most of all), and your RAM. If you can't adjust the CPU blck multiplier only then you will be very limited with how far you can actually overclock. The front BUS OC is definitely the "fine tuning" portion of an overclock whereas the blck multiplier for the CPU is the "meat and potatoes" of you CPU being OC'd. as far as the other things you asked about, I'm sorry I wouldn't be the best to tell you. But, I wouldn't even bother with changing them if all you can OC is the Front BUS.
